Class 6 Maths Understanding Elementary Shapes Measuring Angles

Measuring Angles

The one complete turn is called one revolution and it is divided into 360 equal parts. Each part is a degree. We can measure the angle by using a protractor.

A protractor is divided into 180 equal parts and each part is equal to a degree. The markings start from 0° on the right side and ends with 180° on the left side, and vice-versa.
