Draw an angle of with the help of a protractor and bisect it. Measure each angle.
Steps of Construction:
1. Make an angle of by using a protractor
2. Take B as the centre and draw an arc which intersects BC and BA at E and D respectively.
3. Take D and E as centres and draw arcs (without changing the span of the compass) such that they intersect each other at point F.
4. Draw a line BG which passes through F.
