Measuring Angles

The video tutorial explains how angles can be measured using degrees. It introduces the concept of a degree as one of 360 equal parts of a circle. The tutorial describes how to measure an angle by determining how many degrees fit within the angle's opening. An example is provided where an angle measures 30 degrees. The lesson concludes by reinforcing the method of measuring angles by counting the number of degrees within them.
