How to Draw an Impossible Triangle

In this instructable, I will be showcasing how to draw an Impossible Triangle, also known as the Penrose Triangle. An impossible figure is a shape that cannot exist in reality, a nonsensical figure, and there are hundreds, but the triangle is one of the more basic ones. You don't really have to be a pro at drawing to make it. I chose to make this instructable because it's simple, all you really need is a pencil and paper, and it's dimensions are very easy to change if needed.

For this instructable, you'll need a pen/pencil, a ruler to draw with, and a regular sheet of computer paper.

Add a base line to start the triangle. Make sure not to make it too close to the top of the page.

At each end of the base line, make small diagonal lines as shown.

At the end of each of the smaller lines from the previous step, add longer diagonal lines as shown.

Connect the 2 lines from the previous step together with a horizontal lines.

From the center intersection on the right, draw a straight horizontal line to the other side, but don't connect them. Leave space as shown in the image.

From the bottom left intersection to the top right intersection, make a diagonal line, but same as the last step, don't connect them.

From the end of the line from the previous step, draw a diagonal line down as shown. Then, from the end of the line from step 5, draw a diagonal line upwards at the same angle from the line from step 6. It should now look like the image shown.

From the intersection at the top left of the triangle, draw a diagonal line downwards, but same again, leave space between the line you're drawing and the line from step 5.

From the end of the line from the previous step, draw a horizontal line connecting it to the line from the opposite side as shown.

Erase the overlapping part of the downwards line from step 7. You should now have what the introduction image showed, an impossible triangle.
