Q5. Construct with ruler and compasses, angles of following measures:
The steps of constructions are:
1. Draw a ray OA.
2. Taking O as the centre and convenient radius, mark an arc, which intersects OA at P.
3. Taking P as the centre and the same radius, cut the previous arc at Q. Join OQ. Thus, ∠BOA is the required angle of 60°.
4. Put the pointer on P and mark an arc.
5. Put the pointer on Q and with the same radius, cut the previous arc at C. Thus, ∠COA is required angle of 30°
