How to construct a 30 degree angle without a protractor?

Answered by admin @ 04/08/2021

Steps of construction :

(i) 30°

Step 1 : Draw a ray AB.

Step 2 : With O as a centre and any radius draw an arc cutting AB at P.

Step 3 : With P as a centre draw an arc at R to make ∠AOC = 60°.

Step 4 : Draw the bisecor of ∠AOC, with P and R as a centre, draw an arc.

Step 5 : Join OD.

Hence, ∠AOD = 30° is the required angle.
