Question

Construct a ∆PQR where QR = 8 cm, ∠Q = 120° and ∠R = 30°.

Answer 1

Steps of construction:

1. Draw a line QR = 8 cm.

2. Make an angle 120° ∠AQR at point Q with the help of compass.

3. Make ∠BRQ = 30° at point R with the help of compass.
4. Line AQ and BR intersect at point P each other.

Thus ∆PQR is required triangle.
