Two circles intersect at A and B. P is a point on produced BA. PT and PQ are tangents to the circles. The relation of PT and PQ is
Answer : Option A
Explanation : 
PT2 = PA × PB .........(i)
PQ2 = PA × PB .........(ii)
By (i) and (ii) equation,
we find that,
PT2 = PQ2
∴ PT = PQ
Tangents will be equal.
