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
