Exterior Angles of Polygons

The video tutorial demonstrates how to find the sum of exterior angles of polygons using a visual method. It begins with drawing a pentagon, extending its sides, and cutting and assembling its exterior angles to form a full circle, proving the sum is 360 degrees. The process is repeated with a hexagon, reinforcing the concept that the sum of exterior angles of any polygon is always 360 degrees.
