I don't know what a polygon is anymore! I thought that I knew, but it turns out I don't. I mean, a square is a polygon, and so is a triangle. But what about this thing?
Our glossary definition says that a polygon is "a closed 2D shape that has multiple straight (not curved) lines, where every line is touching another line on both ends." And this shape obeys that definition. But it has an infinite number of sides! It also has an inside and an outside, which I guess is important.
What do you think? Is this a monster, or just an unusual example of a polygon?
