you call a seven sided shape a heptagon.
A shape with five sides would be a pentagon, but a shape can not have 5 right angles. Squares and Rectangles are both shapes with 4 sides and 4 right angles. They are the only shape with the same amount of right angles as there is sides.
A 30 sided shape is called a Triacontagon.
It is called a trapezium.

A 101-sided shape is called a "hectacontakaihenagon."

A nine sided shape or polygon is called a nonagon.
Oh, dude, that's easy. A 200-sided shape is called a "dihectakaitetragon." Yeah, I know, it sounds like something out of a sci-fi movie, but hey, math can be weird like that. So next time you're doodling and accidentally draw a 200-sided shape, you can impress your friends by dropping that fancy term on them.
