PLEASE help me with the following question Share with your friends Share 0 Atul Shaw answered this Dear student, 17. (i) Let PQRS be a quadrilateral with PR and QS be its diagonals. In ΔPQR, PQ + QR > PR (Sum of any two sides of a triangle is greater than the third side) In ΔPRS, RS+ PS > PR Adding both the equation, we get (PQ+QR+RS+SP)>PR+PR ⇒ (PQ+QR+RS+SP)>2PR Similarly, it can be proved that (PQ+QR+RS+SP)> 2QS by taking the triangle PQS and QRS. Now adding these two results, we get 2(PQ+QR+RS+SP)>2(PR+QS) For remaining queries we request you to post them in separate threads to have rapid assistance from our experts.
