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).

| 100 | Regular Hectagon | Internal Angle 176.40°External Angle 3.60° |
| 1000 | Regular Chiliagon |  A whole regular chiliagon is not visually discernible from a circle. The lower section is a portion of a regular chiliagon, 200 times as large as the smaller one, with the vertices highlighted.Internal Angle = 179.64° |
| 10000 | Regular Myriagon | Internal Angle = 179.96° |
| 1,000,000 | Regular Megagon |  Even if drawn at the size of the Earth, a regular megagon would be very difficult to distinguish from a circle.Internal Angle = 179.99964° |
