Solution

The below given steps will be followed to construct an angle of 15°.

Step I:- Draw the given ray PQ. Taking P as centre and with some radius, draw an arc of a circle which intersects PQ at R.

Step II:- Taking R as centre and with the same radius as before, draw an arc intersecting the previously drawn arc at point S.

Step III:- Taking R and S as centre and with radius more than 1/2RS, draw arcs to intersect each other at T. Join PT.

Step IV:- Let it intersect the arc at U. Taking U and R as centre and with radius more than 1/2RU, draw an arc to intersect each other at V. Join PV which is the required ray making 15° with the given ray PQ.
