Solution



Construction:

Step 1: Drawn a line. Marked P and Q on the line such that PQ = 6 cm.

Step 2: At P, drawn O ray PX making an angle of 115° with PQ.

Step 3: At Q, drawn another ray QY making an angle of 40° with PQ.

Marked the point of intersection of the rays PX and Q Y as R.

PQR is the required triangle.
