Interior and Exterior Angles Test Your Knowledge

This video tutorial covers the concepts of interior and exterior angles in polygons. It explains how to calculate these angles, find their sums, and determine the number of sides in a polygon given an angle. The video provides examples using triangles, squares, pentagons, and hexagons to illustrate the calculation of interior angles. It also discusses the properties of exterior angles, emphasizing that they always sum up to 360°. The tutorial concludes with practice questions to reinforce the learning material.
