Two
tangents `T P`
and `T Q`
are drawn
to a circle with centre `O`
from an
external point `T`
. Prove
that `/_P T Q=2/_O P Q`
.
Text Solution
Verified by Experts
We know that, the lengths of tangents drawn from an external point to a circle are equal.
TP=TQ
In triangle TPQ,
TP = TQ
`/_`TQP=`/_`TPQ
(In a triangle, equal sides have equal angles opposite to them)
...
