Exploring Shapes and Angles

This video tutorial introduces the concept of angles in various shapes, starting with triangles, which have three sides and three angles. It then explores rectangles, which have four sides and four angles, and other quadrilaterals like trapezoids. The tutorial further explains how to identify and count angles in these shapes. Finally, it introduces pentagons and hexagons, explaining their properties and encouraging viewers to draw these shapes to understand their angles and sides.
