Question

Plzz tell the answer of i promised who give corrrect answer i mark brainlist

Answer 1

Step-by-step explanation:

angle ABP = angle QBP since BP is the bisector of angle ABC

now, angle ABP = angle BPQ since alternate angles as AB || PQ

therefore angle QBP = angle BPQ

therefore triangle BPQ is an isosceles triangle.

Hence proved.
