Those weird shapes which no-one really likes. JUST LOOK AT THEM, Do they look geometrical? Yes cuz they are something geometrical, duh noob. Triangles' 3d form are called a pyramid which well, have 5 sides, one under, none above, and 4 at each side. Which sums up to 5 sides. Otherwise. You should read the next sentence: You've wasted your time( wasted time ) on reading this, now go away, YOU KNOW WHAT triangles ARE DO YOU?
The most evil, awful, terrifying, omnipotent horrors to ever exist in the known universe. Their evil outweighs that of the devil himself. They are everywhere, there is no escape. Their servants come in the form of collage and high school geometry teachers, spreading pain and suffering. Fear them. FEAR THE TRIANGLES.
