## What is a 100000 sided shape?

Convex, cyclic, equilateral, isogonal, isotoxal.

A megagon or 1 000 000-gon is a polygon with 1 million sides (mega-, from the Greek μέγας megas, meaning “great”).

Even if drawn at the size of the Earth, a regular megagon would be very difficult to distinguish from a circle..
