Polygon Angles and Properties

The video tutorial covers Chapter 7, focusing on finding angles in polygons. It explains the interior and exterior angles of polygons, using formulas to calculate their sums. The tutorial provides examples, such as calculating angles in a regular hexagon, and demonstrates how to determine the number of sides in a polygon given the sum of its interior angles.
