Know : Triangle, Square, Pentagon… How long it goes?

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.

regular polygon is a polygon that is equiangular (all angles are equal in measure) and equilateral (all sides have the same length). 

How many you know before? How to draw a perfect polygon with 10 sides? Know more here… (To see how to draw them? Scroll down the table)

1000 Regular Chiliagon  Chiliagon.pngA 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  Circle - black simple.svgEven if drawn at the size of the Earth, a regular megagon would be very difficult to distinguish from a circle.Internal Angle = 179.99964°
