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 `1/2`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.
