Question
Using the protractor, draw a right angle. Bisect it to get an angle of measure $45^\circ .$
✓
Answer
Steps of construction:
1. Draw an angle $A B C$ of $90^{\circ}$.
2. With $B$ as the centre and any radius draw an arc which intersects $A B$ at $P$ and $B C$ at $Q$.
3. With $P$ as center and radius more than half of $PQ$ draw an arc.
4. With $Q$ as center and same radius draw an arc which intersects the previous arc at $R$.
5. Join $RB.$
Therefore $\angle\text{RBC}=45^\circ$
