Construct an angle of
On bisecting 45°, we get
Steps of Construction
1. Draw a line segment OA.
2. At A, draw ∠AOE=90° , using ruler and compass.
3. With B as centre and radius more than half of BD, draw an arc.
4. With D as centre and same radius draw another arc which cuts the previous arc at F.
5. Join OF. ∠AOF=45°
6. Now with centre B and radius more than half of BC, draw an arc.
7. With centre C and same radius draw another arc which cuts the previously drawn arc at X.
8. Join OX
Therefore, OX is the bisector of ∠AOF.
