A circle c touches a larger circle C from the inside at point P. The point Q is a point different from P on c. The tangent at c at point Q intersects C at points A and B. Prove that the straight line PQ halves the angle APB.

I would start with drawing the circles and locate the points Q, P, A & B. Now I would think about circle-tangent theorems. Continue......
