From the figure, the lines which lines are parallel to each other are:
AB is a diameter of the circle and A, P, B, R are four points on the circle. The lines AP, RB intersect at Q. Find ∠BPR.
Use the following information to answer the next question.
In the given figure, QA and RB are the altitudes of sides PR and PQ (respectively) of ΔPQR such that RB = QA.
If BQ = 3 cm, AP = 3 cm, and AQ = 4 cm, then what is the perimeter of ΔPQR?
