Optical illusion

 

Today I made an infinite triangle. I had never made an infinite triangle before but it was pretty easy. First you need to draw an equilateral triangle. Next you need to make triangles in the corners by adding a line. After that you want to attach each corner to the other but so the lines are parallel to the original triangle. Next draw three new lines parallel to the nner triangle. That is it but you might not see it because there is a few lines to rub out. For better instructiontions go here.
