Answer 2

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.
