This document is a presentation on regular polygons presented by a student named Asawthy Ajayan. It defines regular polygons as polygons where all sides and angles are equal. It provides examples of regular polygons including equilateral triangles, squares, a regular polygon with 6 sides, and regular hexagons. Diagrams and properties of each regular polygon are given, such as side lengths and angle measures.
