Triangle Δ (3), Square (4), Pentagon (5), Hexagon (6), Heptagon(7), Octagon(8)… How long it can go?
A Megagon is a shape with 1,000,000 equal sides. Even if drawn at the size of the Earth, a regular megagon would be very difficult to distinguish from a circle.
A regular polygon is a polygon that is equiangular (all angles are equal in measure) and equilateral (all sides have the same length).
