Question

The diagonal PR of a quadrilateral PQRS bisects the angles P and R, then

  1. PS = PQ and QR = RS
  2. PS = PR and SR = QS
  3. PQ = SR and QR = PS
  4. PS = RS and PQ = QR

hintHint:

In this question we have to determine the correct statement from the given options. The sides given in the options belongs to increment space P R S space a n d increment space P R Q So we need to prove the two triangles congruent first. Given that PR bisects the angles  P and R , that means angle S P R equals angle Q P R space a n d space angle S R P equals angle Q R P , and PR is common. After proving the triangles congruent we will get the correct statement.

The correct answer is: PS = PQ and QR = RS


    The diagonal PR of a quadrilateral PQRS bisects the angles P and R, then - PS = PQ and QR = RS.
