This document introduces polygons and provides examples of different types of polygons. It defines a polygon as a two-dimensional, closed figure made up of three or more straight line segments that meet at vertices. Common polygons include triangles, quadrilaterals, pentagons, hexagons, and others up to dodecagons. Each polygon type has a specific number of sides and various sub-types are described.
