polygon
In the vector type of GIS internal data organization spatial data are conveniently divided into point, line and polygon types. Some vector GIS store information in the form of points, line segments and point pairs; others maintain close lists of points defining polygon regions.

Geometrical figure that is circumscribed by straight lines.

pol′i-gon, n. a plane figure bound by a number of straight lines: a figure of many angles.—adjs. Polyg′onal, Polyg′onous. [L.,—Gr. polygōnon—polys, many, gōnia, a corner.]

polygon
A geometrical figure of any number of sides more than four; regular or irregular. In fortification the term is applied to the plan of a piece of ground fortified or about to be fortified; and hence, in some countries, to a fort appropriated as an artillery and engineering school.

polygon
The name applied to the many-angled forms in which the outer walls of all fortified places are built.

A polygon is a closed two-dimensional shape. It usually has three sides/corners or more. It has a number of edges. These edges are connected by lines. 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. The monogon is a theoretical figure that cannot exist - it has only one side and one edge.

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.
