Two circles touches internally at a point P and from a point T ,the common tangent at P , tangent segments TQ and TR are drawn to the two circle Prove that TQ=TR
Question should be:
Two circles touches externally at a point P and from a point T, the common tangent at P, tangent segments TQ and TR are drawn to the two circle Prove that TQ=TR.

Proof:-
Let the circles be C1 and C2
C1 and C2 touch each other externally at P
From T, tangents are drawn
Tangent TQ on C1 and tangent TR on C2, common tangent is TP
Since, the tangents drawn from an external point are equal, we have
TP =TQ and TP = TR
Therefore, TQ = TR.
