Angle Tester 
Q1: How do we make equal angles? 
Sol: We can use the divider from the geometry box to make equal angles. Measure an angle with the help of the divider and make another angle of equal measurement. The divider is also called the angle tester.

Q2: How can you make your own angle tester? 
NCERT Solutions for Class 5 Maths - Shapes and Angles

Sol: For this, you need following materials; cardboard strips, drawing pins or split pin.Take two cardboard strips of same size. Join their one ends with the help of the drawing pin or split pin. Move the strips from joint so that they can freely rotate. Your angle tester is ready.

Q4: Can you guess how many degrees is the angle which is?
(i) ½ of a right angle .
Sol:
We know that the right angle is equal to 90 degrees.
Then, ½ of a right angle = ½ × 90 degrees.
= 1 × 45
= 45o

(ii) 1/3 of a right angle .
Sol:
We know that the right angle is equal to 90o.
Then, 1/3 of a right angle = 1/3 × 90o
= 1 × 30
= 30o

(iii) 2 times of a right angle.
Sol:
We know that the right angle is equal to 90o.
Then, 2 times of a right angle = 2 × 90o
= 180o
