For such large numbers as this, hust call it a "200-sided polygon". This is simpler, and more useful, than inventing fancy names for figures of different number of sizes.

A shape with three linear sides and one curved side can be drawn, but such a shape has no specific name.
A 10 sided polygon is called a decagon (deca meaning 10).
a 200gon. for shapes that don't have an official name, with an official name being decagon, pentagon, hexagon, etc. just insert the number of sides before the 'gon'
Extend any straight side of a shape. The angle made by that side with the adjacent side of the shape is an exterior angle. Its value is 180 degrees less the interior angle.
A 7 sided shape is a heptagon
dodecagon
Decagon
An octagon.
pentadecahedron

nonagon
Isasakaitateragon
