In the given figure, two circles intersect each other at the points A & B. If PQ & PR are tangents to circles at point P and BA is extended to meet at P, prove PQ = PR
PQ2 = PA×PB
PR2 = PA×PB
⇒PQ2 = PR2
⇒PQ = PR
In figure PO ⊥ QO. The tangents to the circle at P and Q intersect at a point T. Prove that PQ and OT are right bisectors of each other.
