Classify Polygons

In geometry, a figure that lies in the plane is called a plane figure. A polygon is a closed plane figure with the following properties:

It is formed by three or more segment called sides.
Each side intersects exactly two sides, one at each endpoint, so that no two sides with a common endpoint are collinear.

A polygon is convex if no line that contains a side of the polygon contains a point in the interior of the polygon.

Polygon that is not convex is called non-convex or concave.
