Construct a quadrilateral PQRS in which PQ = 4 cm, QR = 5 cm ∠P = 50°, ∠Q = 110° and ∠R = 70°.
Steps of construction:
Step I: Draw PQ = 4 cm.
Step II: Construct ∠XPQ = 50° and ∠PQY = 110°.
Step III: With Q as the center and radius 5 cm, cut off QR = 5 cm.
Step IV: At R, draw ∠QRZ = 70° such that it meets PX at S.
