Q3. Draw a right angle and construct its bisector.
The steps of construction:
(a) Draw a line PQ and take a point O on it.
(b) Taking O as the centre and convenient radius, draw an arc that intersects PQ at A and B.
(c) Taking A and B as centres and radius more than half of AB, draw two arcs which intersect each other at C.
(d) Join OC. Thus, ∠COQ is the required right angle.
(e) Taking B and E as the centre and radius of more than half of BE, draw two arcs that intersect each other at point D.
(f) Join OD. Thus, the OD bar is the required bisector of ∠COQ.
