Exterior Angles Of Polygons

This video tutorial explains the concepts of interior and exterior angles in polygons. It begins with an introduction to angles in polygons and references a previous video for further understanding. The tutorial then delves into the nature of exterior angles, explaining their relationship with interior angles. It provides a detailed calculation of angles in a nonagon, demonstrating how to find both interior and exterior angles. The video highlights that the sum of exterior angles in any polygon is always 360 degrees, which is useful for determining the number of sides in a polygon. Key formulas for calculating these angles are summarized, and viewers are encouraged to engage with the content and ask questions.

If the exterior angle of a regular polygon is 45 degrees, how many sides does it have?
