Answer:

Let us suppose that ABQ is a right angle triangle such that triangle is right angled at B.

Given

          sinB = sinQ

Now

sinB = AQ/BQ ...........1

sinQ = AB/BQ ...........2

Since sinB = sinQ

then from equation 1 and 2, we get

      AQ/BQ = AB/BQ

=> AQ = AB

Therefore triangle ABQ is isoscales triangle.

 So Angle B = Angle Q

Hence proved.
