Polygon

In elementary geometry, a polygon is a plane figure that is bounded by a finite chain of straight line segments closing in a loop to form a closed chain or circuit...

In geometry a simple polygon is defined as a flat shape consisting of straight, non-intersecting line segments or "sides" that are joined pair-wise to form a closed path. If the sides intersect then the polygon is not simple.

The definition given above ensures the following properties:

A polygon encloses a region (called its interior) which always has a measurable area.

The line segments that make-up a polygon (called sides or edges) meet only at their endpoints, called vertices (singular: vertex) or less formally "corners".

Exactly two edges meet at each vertex.

The number of edges always equals the number of vertices.
