Step-by-step explanation:
angle 1=angle 3(alternate angles)
since angle1=angle3
therefore BPQ is isosceles triangle

Step-by-step explanation:
∠1 = ∠2 [because P is the bisector of ∠ABC]
∠1 = ∠3 [because alternate interior ∠'s w.r.t AB || PQ and t-> BP]
=> ∠2 = ∠3 [because they both are equal to ∠1]
In a triangle if opposite angles are equal to each other, their corresponding sides are also equal to each other.
Since ∠2 = ∠3, BQ = PQ
Therefore, BPQ is an isosceles triangle
