Q5. Construct with ruler and compasses, angles of following measures:
The steps of constructions are:
1. Draw a line PQ and take a point O on it.
2. Taking O as the centre and convenient radius, mark an arc, which intersects PQ at A and B.
3. Taking A and B as centres and radius more than half of AB, draw two arcs intersecting each other at R. Join OR. Thus, ∠QOR = ∠POR = 90°.
4. Draw OD the bisector of ∠POR. Thus, ∠QOD is required angle of 135°
