Polygons

This geometry video tutorial provides a basic introduction into polygons. It explains how to identify if a figure is a regular polygon from those that are not polygons. Polygons have a 2D shape, they are closed figures, and do not contain intersecting lines and open sections. This video discusses different types of polygons such as triangles, squares, rectangles, rhombuses, trapezoids, quadrilaterals, pentagons, hexagons, heptagons, octagons, nonagons, and decagons. it explains how to calculate the sum of the interior angles of a polygon and how to determine the measure of the interior angle of a regular polygon as well as the exterior angle using a simple formula. This geometry video contains plenty of examples and practice problems.
