Expert Answer:

PT is a tangent drawn at a point where the two circles tough internally.

Now for the samller circle

TP = TQ         (Tangents from an external point are equal) ........(1)

Similarly for the larger circle

TP = TR          (Tangents from an external point are equal)  .........(2)

Using (1) and (2)

TQ = TR
