Angles

The video tutorial introduces the concept of angles, explaining that they are measured in degrees and can be thought of as turns. It covers the four types of angles: acute, obtuse, reflex, and right angles. The tutorial also explains how to measure angles using a protractor and how to calculate angles in shapes like quadrilaterals and triangles. Examples include squares, kites, rectangles, rhombuses, and different types of triangles such as equilateral, isosceles, scalene, and right-angled triangles. The video concludes by encouraging viewers to find right angles around their homes.
