Question

In the figure shown below, if PQ 20 cm and angle QPR = angle SPR, then QR=?

Answer 1

QR = 20 * SR/PS  , Data is insufficient   to find numerical value of  QR

Step-by-step explanation:

∠QPR = ∠SPR

=> PR is angle bisector

The "Angle Bisector" Theorem says that an angle bisector of a triangle will divide the opposite side into two segments that are proportional to the other two sides of the triangle.

=>  QR/PQ   =  SR/PS

=> QR = 20 * SR/PS

Hence Data is insufficient   to find numerical value of  QR
