How to find the individual measure of interior and exterior angles for a nonagon

The video tutorial explains the properties of regular polygons, focusing on nonagons. It covers the calculation of both interior and exterior angles, emphasizing that the sum of exterior angles is always 360 degrees. The tutorial also highlights the concept of supplementary angles, where interior and exterior angles add up to 180 degrees.
