Polygon

Plane figure bounded by line segments

A polygon is a closed two-dimensional shape. It is a simple curve that is made up of straight line segments. It usually has three sides and three corners or more.

Polygons: open (excluding its boundary), boundary only (excluding interior), closed (including both boundary and interior), and self-intersecting

It could also be referred to as 'A closed plane figure bound by three or more straight line segments'. It has a number of sides, also called edges. A square is a polygon because it has four sides. The smallest possible polygon in a Euclidean geometry or "flat geometry" is the triangle, but on a sphere, there can be a digon and a henagon.

If the edges (lines of the polygon) do not intersect (cross each other), the polygon is called simple, otherwise it is complex.

In computer graphics, polygons (especially triangles) are often used to make graphics.
