Question

In triangle PQR, a line AB||QR cuts PQ at A and PR at B. If QB bisects angle ABR, then


A. QR = BR

B. QR = QB

C. AB = AQ

D. None of these​

Answer 1

Step-by-step explanation:

i think that option C is correct

Answer 2

(a) QR=BR

BEcause or=BR means it is a isosceles triangle. then the base angles should be equal and same with the triangle qbr

as angle ABQ= angle RBQ

also angle ABQ=BQR(adjacent angle)

by this angle RBQ=BQR.

so the base angles are equal so triangle QBR IS is isosceles
