By Step Instructions For Drawing The Impossible Triangle
1. Begin by drawing a small equilateral triangle, that is, a triangle with sides of equal lengths. This will form the opening in the middle of the impossible triangle.
2. Extend a short, straight line diagonally from each of the triangle’s points. These lines will form the basis of the impossible triangle’s three dimensional appearance.
3. From the uppermost diagonal line, draw a straight line parallel to the side of the small triangle. Then, from this line, draw another straight line parallel to the bottom of the small triangle.
4. Draw a straight, horizontal line from the lowest of the original diagonals. This line should be parallel to and equidistant from the other two horizontal lines.

The Most Famous Impossible Shapes
Four of the most well-known impossible shapes are the Penrose triangle, Penrose stairway, Freemish crate and the impossible trident . The Penrose triangle, aka the tribar, is named after physicist Roger Penrose. Penrose didn’t create it that was the work of a Swedish artist named Oscar Reutersvärd, who made it out of a set of cubes in 1934. But after Penrose published a drawing of the triangle in a 1958 article in the British Journal of Psychology, which he co-wrote with his father, Lionel, it became very popular. In 1982, the Penrose triangle appeared on a Swedish postage stamp to honor native son Reutersvärd .
The Penrose stairway is a staircase that makes four 90-degree turns. When you first glance at it, it looks like a staircase that runs in a square. Odd, yes, but still a traditional set of stairs you can climb. But when you look more closely and imagine yourself walking on it, you quickly see no matter how many times you climb the stairs in that square, up or down, you never get any higher or lower or anywhere, for that matter! The Penrose men also published a drawing of this stairway in their 1958 paper .
The Freemish crate first appeared in the 1958 lithograph “Belvedere,” created by Dutch artist M.C. Escher. A man is sitting on a bench, holding the crate the bench sits at the base of an enormous structure. The crate is also known as Escher’s cube or Hyzer’s illusion .
How Impossible Shapes Inspire Art
Impossible objects are fascinating. You can study them for long periods of time, tracing their lines, trying to figure out just where the “trick” is that makes them look real, yet unreal, at the same time. No wonder they often inspire artists to re-create them. Probably the most famous artist in the world of impossible constructions is M.C. Escher.
Escher, born in the Netherlands, was a talented graphic artist who produced nearly 450 lithographs, woodcuts and wood engravings during his lifetime, plus more than 2,000 drawings and sketches. He was fascinated with impossible objects, and helped popularize the Penrose triangle, which he incorporated into many of his works. One of these is “Waterfall,” a lithograph of a waterway zigzagging uphill and ending in a waterfall. The waterfall actually serves as the short sides of two Penrose triangles, although you don’t necessarily realize this unless you’re looking for it .
Lionel and Roger Penrose’s Penrose stairway also caught his fancy. If you carefully inspect Escher’s famous print “Ascending and Descending,” you’ll quickly see the Penrose stairway inspired this print .
Many other artists around the world become enamored of impossible objects. A polished aluminum sculpture version of the Penrose triangle, for example, was created by Brian McKay and Ahmad Abas in 1997 it sits in East Perth, Australia’s Claisebrook Square . And don’t forget the Penrose triangle was originally created by an artist, the Swede Oscar Reutersvärd.

The Impossible Triangle Optical Illusion: Draw And Build It
Is your child fascinated by magic tricks? Get ready to unleash your inner magician as you explore how our eyes play tricks on us. In this activity, youll create your very own optical illusion: the impossible triangle!
An optical illusion uses patterns, color, and light to make images that confuse our brains. How does it work? Well, when our eyes gather information from the world around us, our brains job is to make sense of it. To understand what our eyes are seeing, our brains create something called a perception. But optical illusions actually cause our perceptions to be incorrect! They trick our brains into thinking we see something thats not actually the true image.
Optical illusions are fun to explore! This activity highlights the optical illusion triangle. This is an object that can be drawn but cannot exist in 3-D formits actually impossible! And thats how it got its nickname of the impossible triangle. For our first optical illusion, well guide your child to do the impossible as they create a model of the impossible triangle using building blocks. Then, well teach them how to draw the optical illusion triangle on paper. Get ready for some mind-bending fun!
How Do I Draw Impossible Shapes
Admit it. You’re dying to try your hand at drawing an impossible shape. That’s not surprising. Remember how much fun it was as a kid when someone first showed you how to draw a cube? You’d draw one square, then another one that was half on top of the first, then connect them with diagonal lines. Voilà a cube!
While there are many complicated impossible shapes that would be difficult for most people to draw, you can use one easy method to create an impossible shape from many common forms: squares, triangles, stars and pentagons. Let’s try a triangle :
- Extend a line off of each corner.
- Draw another line off each of those extensions that extends a bit over the corners.
- We’re almost finished! At the end of each line, draw a short, 45-degree angle that lines up with the opposite side.
- Now the fun part: Connect the lines, and you’ll have an impossible shape!
Use this basic set of instructions to create impossible shapes from other forms. It should be pretty easy.

The impossible triangle, also called the Penrose triangle or impossible tribar, was first drawn by a Swedish artist by the name of Oscar Reutersvärd in 1934.
It was used in the work of psychiatrist Lionel Penrose, mathematician Roger Penrose, and Dutch mathematical artist M.C. Escher, as well as other artists.
The shape has been described as “impossibility in its purest form.”
The impossible triangle is a type of optical illusion – an image that, because of the perception of the eyes and brain, differs from reality.
Impossible objects are optical illusions in which a two dimensional figure , is interpreted by the brain to represent a three dimensional object – one that cannot really exist due to its physical proportions.

Look closely at the impossible triangle, and you may see that its sides connect in unusual ways.
While impossible objects cannot exist in the real world – that’s why they are called impossible – artists have put forth efforts to approximate them.
An outdoor sculpture displayed in East Perth, Australia, for example, assumes the appearance of an impossible triangle when viewed from a certain angle. When viewed from other angles, however, it is apparent that the lines of the “triangle” don’t actually connect.
Psychologists and other scholars have long been interested in optical illusions.
All you will need is a pencil, pen, or marker, and a sheet of paper.

Select the Pencil tool. Move the mouse along the top of the long side of the rectangle until you see a blue dot. That is midpoint. Draw a line from one side to the other on this midpoint. Then, do the same in the two sides of the line you just created to divide the rectangle into fourths. If you have difficulty making the lines, Click on the tool that looks like a tape measure and on the pop up menu, select the tool with the “3” on it called dimensions. Then, you could add a dimension to any two points and check easily.
By Step Drawing The Penrose Triangle
1-For a Penrose triangle, draw a basic triangle with three equal sides. If you have a ruler, use it for each step.
KEY-DETAIL PRACTICEUsing a ruler, first draw a mini Penrose outline to become familiar with the formula
2-From each edge tip, continue the triangles lines just a little bit farther, having them all angling in the same direction, for example, to the left.
3-From this extended tip, attach a line parallel to the adjacent sides line.
4-From that new line, make a small check-mark edge.
5-From that check mark, and again parallel to the side line, make sure the gaps between each triangle are equally spaced around all edges.
6-Connect any open gaps or corners.
7-The inner structure gets the value gradient. Youll shade from dark to light, and you should have three inner edges. At the top of the inner edge, start with your darkest value and gradually lighten up as you reach halfway down this track.
8-Repeat for the remaining two corners.
Artist TrickPlan your shading out ahead of time to prevent two mid-tones or two darks from being adjacent to each other.

By Step Instructions For Drawing Impossible Stairs
1. Begin by drawing three connected straight lines, one vertical and the remaining lines diagonal. Notice that the lines vary in length. These lines outline the base of the impossible stairs.
2. Draw straight vertical lines of different lengths from the corner and end of the lines. These form the sides of the walls comprising the stairs.
3. Draw a series of short, connected, straight lines. The lines should be arranged in a zigzag pattern, forming the edge of the stairs and connecting two form the vertical lines.
4. Draw a second set of connected straight lines, forming a zigzag pattern, to connect the remaining vertical lines. This forms the edge of another side of the stairs.

8. Draw short straight lines extending at a diagonal angle from the third zigzag line. The lines should be parallel to one another. Then, connect each line to the line before it using short straight lines. This forms the third set of stairs.
9. Extend short straight lines from the points of the remaining zigzag line. Connect these using straight lines, forming the final set of stairs.
10. Color your impossible stairs, shading them as pictured in our example in order to enhance the three dimensional nature of the optical illusion.

Fill Shapes And Tweak With The Gradient Tool
Once we have our three shapes, select one of them and apply a gradient fill. Grab the Gradient tool and drag the gradient so the darker side of the gradient runs into what would look like the inner corners of the triangle illusion. Once more, check out the video at the top of this post to see exactly how this triangle and gradient effect comes together.

How To Build And Draw An Impossible Triangle
First, lets build!
Step 1: Collect the building brick base and the pieces youll need to build the impossible triangle. Its helpful to use building bricks that are all the same color.
Step 2: Place the 2×10-stud brick on the base.
Step 3: Connect the 2×2-stud bricks. Add the stack to one end of the 2×10-stud brick. You should have a structure that looks like an L now.
Step 4: To complete your optical illusion triangle, add the 2×8-stud building block at the top. It should face away from the bottom brick. From an angle, the structure should look like a 7.
Step 5: Now its time to trick your brain! Move around, looking at your optical illusion triangle, until it looks like the sides are connected. To help your brain perceive the illusion, try closing one eye , moving closer or farther away, or moving side to side! Did it work?
Now, lets draw!
Step 1: On a blank piece of paper, use a pencil to draw a triangle with equal sides. This type of triangle is called an equilateral triangle. Its helpful to use a ruler to help measure equal sides and make straight lines.
Step 2: Next, draw a line in each corner to make three smaller triangles. New lines in the picture are highlighted with yellow for clarity.
Step 3: Now, connect the small triangles. Draw three lines that are parallel to the original triangle. Now you can see a smaller triangle in the center.
Step 5: Next, were going to erase. The dotted lines in this image show you which lines to erase.

Draw A Penrose Triangle
A Penrose triangle is an “impossible object” – that is, a 2-d image that represents a 3-d object that would be impossible to actually construct as shown. This instructable will show you how to draw one using two methods – one freehand and the other using a compass and straightedge . If you’d like to skip right to the beginning of the compass and straightedge process, go directly to step five. Do not pass “go” and do not collect $200. -)(Note: I am aware that instructions for drawing a Penrose triangle have already been uploaded, but I chose to upload this anyway because I included compass and straightedge instructions.

The illusion is created as the brain tries to perceive the two dimensional drawing as a three dimensional figure.
What makes these stairs so impossible? Each flight of stairs on its own appears normal. It is the connections between the stairs, however, that make the figure impossible in real life.
The staircases appear to connect at right angles to form a circuit yet, a person could seemingly ascend or descend the stairs forever without getting any higher or lower.
Scroll down for a downloadable PDF of this tutorial.
The Penrose stairs were developed by Lionel Penrose, a psychiatrist, and his son Roger Penrose, a mathematician, in 1959. The pair are also responsible for the Penrose or impossible triangle, on which the impossible stairs are based.
The impossible stairs feature prominently in the work of artist M.C. Escher, including the lithographs Ascending and Descending and Waterfall. Swedish artist Oscar Reutersvard employed similar impossible objects.
Would you like to draw impossible stairs? This easy, step-by-step drawing tutorial is here to help. All you will need is a pencil, pen, or marker and a sheet of paper. You may also wish to shade your finished drawing. Now, it’s time to get to stepping.

Grab the Star tool and use the down arrow key as you drag out the star to get rid of sides of the star until you have nothing but a triangle left. The goal here is to create a shape similar to what you see in the screenshot. I used a combination of Transforming, Duplicating, and the Pathfinder to create a precise series of paths that will create the perfect basis of guides in the next step.
