How To Draw An Impossible Triangle Optical Illusion – Impossible Shapes

How To Draw An Impossible Triangle Optical Illusion – Impossible Shapes

Hi this is Ethan Nguyen here from and in this lesson, you’re going to learn how
to draw a simple optical illusion called, “the impossible triangle.” The reason is this illusion is called “the
impossible triangle” is because it is a shape that can not actually exist in real life. But despite the name, this illusion is actually
very simple to draw. So let’s get started! Step 1 – Drawing The Layout The first step is to draw a simple triangle.
Try to make all the sides as uniform as possible. Next within the triangle you just drew, draw
the 3 sides again to form a smaller triangle. The gap between the larger and smaller triangle
will determine the thickness of your impossible triangle. I try to keep this distance relatively
thin so that my drawing does not get too crowded. Repeat this process one more time to create
a third (and even smaller) triangle. Now go to each of 3 the diamond shapes at
the outer corners of your drawing and put a short line through the middle of each. And that’s it! That’s all the lines we have
to make. Our impossible triangle is in there somewhere. We just have to make it visible. Step 2 – Make The Triangle Visible First, erase the 3 corner tips of the larger
triangle. Notice that we now have a large triangle-like shape at the outer edge of the
drawing. And we also have a small triangle at the very center. Let’s ink in these 2 shapes. I’m using a 0.5
Copic multiliner pen. The ink on these pens take a few seconds to
dry fully so be careful not to smudge them when you are drawing. Now we just have to ink in the rest of the
drawing. There’s a lot of lines here so it can get a bit confusing. The best way to think about this is to imagine
you are trying to get from the large triangle to the small triangle using these roads. Here’s what I mean. Let’s start with this
corner. Here we have a choice of 2 roads. For the first one, it doesn’t matter which
road you pick. So let’s just go with the one on the left. Follow this road down until you get to the
far end of the small triangle and then make a turn to connect to it. Now let’s do the same thing for this corner.
Again, you have 2 roads to choose from. But since this one is already used, we’ll have
to use the other one. And again, once you get to the far end of the small triangle,
make a turn to connect to it. And lastly, we’ll do the same for the 3rd
corner. Now let’s wait for a minute for the ink to
dry and then erase the pencil lines to reveal our impossible triangle. Step 3 – Shading The Triangle going to add a few finishing touches to make
it really pop. I’ll use a 1.0 size pen to create a thick
outline at the outer edge and the center of the triangle. And lastly, let’s add some shading. We’ll
use a 2B pencil to put a gradation at the 3 inner corners of the triangle. Then, let’s add a lighter gradation at the
3 outer corners. And we’re all done!

    Thank you for the excellent tutorial I drew two but I believe that my problem exists in needing the right color pencils for shading. Could you possibly suggest an inexpensive brand for me to use. I used my Sigma microns to do the black drawing part.

    Imagine I’m high on kokaine: the impossible triangle can’t exist in our current reality plane, or the paper makes this triangle exist in a 2d structure and may exist in higher reality’s than ours, probably 4d or higher
