Construct a quadrilateral ABCD given that AB = 4 cm, BC = 3 cm, ∠A = 75°, ∠B = 80° and ∠C = 120°.
Steps of construction:
Step I: Draw AB = 4 cm .
Step II: Construct ∠XAB = 75° at A and ∠ABY = 80° at B .
Step III: With B as the centre and radius 3 cm, cut off BC = 3 cm .
Step IV: At C, draw ∠BCZ = 120° such that it meets AX at D .
The quadrilateral so obtained is the required quadrilateral .
