Steps of Construction-

1. Draw a ray OA

2. With the help of protractor, construct ∠AOB = 147°

3. Taking centre O and any convenient radius, draw an arc which intersects the arms OA and OB at P and Q respectively.

4. Taking P as centre and radius more than half of PQ, draw an arc.

5. Taking Q as centre and with the same radius, draw another arc which intersects the previous at R.

6. Join OR and produce it.

Thus, OR is the required bisector of ∠AOB.
