This document provides definitions and examples of polygons, including regular and irregular polygons. It defines a polygon as a closed plane figure formed by three or more line segments. A regular polygon is one where all sides are congruent and all angles are congruent, while examples of irregular polygons do not meet these criteria. Specific polygons are defined by the number of sides, including triangles with 3 sides, quadrilaterals with 4 sides, pentagons with 5 sides, hexagons with 6 sides, and octagons with 8 sides.
