NCERT Solutions for Class 5th Maths Chapter 3 Angles as Turns
Updated on 2026-09-19
About this chapter
A turn is measured against a full circle. Spin round once and come back to where you started — that is one full turn . Half of it is a half turn , and a quarter of it is a quarter turn . When you stop after a turn, the space between where you began and where you stopped is called an angle . Turns add up like fractions. Two quarter turns make a half turn, because 1/4 + 1/4 = 2/4 = 1/2. Two half turns make a full turn, because 1/2 + 1/2 = 1. Four quarter turns also make a full turn, because 4/4 = 1. This is the whole idea of the chapter in one line. Each size of turn has an angle name. A 1/4 turn is a right angle — a square corner, like the corner of your notebook. Less than a 1/4 turn is an acute angle . Between a 1/4 and a 1/2 turn is an obtuse angle . Exactly a 1/2 turn is a straight angl
