Exploring the World of Polygons

This video tutorial covers the basics of polygons, including types like triangles, quadrilaterals, and polygons with more sides. It explains the characteristics of regular and irregular polygons, and how to identify them. The video also teaches how to calculate the sum of interior angles and solve related problems. Finally, it discusses exterior angles and provides methods to calculate them.
