Question
Given below steps of construct a quadrilateral PQRS where PQ = 5.0 cm, QR = 3.0 cm, RS = 4.2 cm, SP = 3.3 cm and which of the following is a wrong step?
(P) Step 1: Draw PQ = 5.0 cm and construct
(Q) Step 2: With P as center and radius SP = 3.3 cm, cut off SP = 3.3 cm along PX.
(R) Step 3: Join. With S as center and radius RS = 4.2 cm, draw an arc.
(S) Step 4: With Q as center and radius QR = 3.0 cm, draw an arc to cut the arc drawn in above step at R. Join QR, RS to obtain the required quadrilateral PQRS.
