Construct a triangle PQR such that PQ = 6 cm, QR = 7 cm and PR = 4.5 cm

Solution:

Steps of Construction:

1. Construct a line PQ of length 6 cm.

2. Taking P as centre, construct an arc of 4.5 cm radius.

3. Taking Q as centre, construct an arc of 7 cm radius which intersects the previous arc at the point R.

4. Now join PR and QR.

Therefore, triangle PQR is the required triangle.
