Question

Using protractor, draw a right angle. Bisect it to get an angle of measure 45°.

Answer 1

Steps of construction:
1. Draw an angle ABC of 90°
2. With center B and any radius, draw an arc which intersects AB at P and BC at Q
3. With center P and Q and radius more than `1/2`PQ draw two arcs, which intersect each other at R.
4. Join RB

∴ `∠`RBC = 45°
