Now onto polygons!

...No, not Porygon from Pokemon

But they do have a lot in common!

You see, Polygons are simply shapes. And Porygon is made completely from different shapes. Hey, it helps me remember ;)

 

Polygons are shapes, all different sizes. They are simple closed curves with sides that are line segments.

Convex and Concave Shapes

How i like to remember the difference between the two, is that concave shapes are caving in, while the convex shapes have structure and do not cave in.
