Question

Draw an angle of measure 147° and construct its bisector.

Answer 1

The below given steps will be followed to construct an angle of 147º measure and its bisector.

(1) Draw a line l and mark a point O on it. Place the centre of the protractor at point O and the zero edge along line l.

(2) Mark a point A at 147º. Join OA. OA is the required ray making 147º with line l.

(3) Draw an arc of convenient radius, while taking point O as centre. Let it intersect both rays of angle 147º at point A and B.

(4) Taking A and B as centres, draw arcs of radius more than AB in the interior of angle of 147º. Let those intersect each other at C. Join OC.

OC is the required bisector of 147º angle.
