Question

Construct ∠AOB = 85° with the help of a protractor. Draw a ray OX bisecting ∠AOB.

Answer 1

Steps for construction:

1. Draw $\angle$AOB = 85$°$ with the help of a protractor.
2. With O as the centre and any convenient radius, draw an arc cutting OA and OB at P and Q, respectively.
3. With P as the centre and radius more than half of PQ, draw an arc.
4. With Q as the centre and the same radius as before, draw another arc cutting the previously drawn arc at a point R.
5. Draw RO and produce it to point X.
Then, ray OX bisects $\angle$AOB.
