Explanation

This is another version of the Impossible Triangle Optical Illusion.

The artist is taking advantage of the 3-D techniques of shading and perspective angles to create this impossible triangle optical illusion. The surfaces and corners of the triangle in this drawing are not in the same position they would be if it were a normal triangle, drawn in proper perspective.

The added shading helps track the surface as intended. Notice the use of different shades at each corner.

The breaks in the middle help to create a more believable impossible form.

Through this 3-D optic illusion we see the possibilities of drawing semi-realistic images of 3-D objects that couldn't possibly be made using right angles.
