Polygon Angles and Properties

The video tutorial covers the concept of polygon angles, starting with basic geometry problems and moving through the calculation of interior and exterior angles in various polygons, including triangles, quadrilaterals, pentagons, and hexagons. It introduces the polygon angle sum theorem and demonstrates how to solve angle problems using this theorem. The video also explores regular polygons and their properties, concluding with practice problems to reinforce the concepts learned.
