Question

Draw an angle of ${132}^{\circ }$ and construct its bisector. [4 MARKS]

Answer 1

Each step: 1 Mark

The steps given below should be followed to construct an angle and its bisector:

i) Draw a line l and mark a point 'O' on it.

ii) Mark a point A ${132}^{\circ }$ to line l with the help of protractor. Join OA.

iii) Draw an arc of convenient radius, while taking point O as the centre. Let it intersect both rays of angle ${132}^{\circ }$ at point A and B.

iv) Taking A and B as centres, draw arcs each of radius more than half of AB so that they intersect each other at C. Join OC.

OC is the required bisector of angle of ${132}^{\circ }$
