A polygon is a 2D shape that obeys these rules:
- It must have 0+ sides
- It must have line segments as edges
- It must be closed
- It must not have any shapes in shapes
- It must not have any cross-overs
An example of this is a square. It has an area of and each side is equal.
Some exotic polygons, such as the henagon and the digon, do not obey the above rules. However, they only exist properly in non-euclidean geometries, and are hence not usually counted among the real polygons.
Other name of polygon is Polysquaron. (By Googleaarex)
