Step-by-step explanation:
given : two tangents PT and PQ are drawn to a circle with centre O from an external point T
To prove:
proof :
we know that the length of the tangent drawn from an external point to a circle are equal
so , TP = TQ
(angle opp to equal sides )
PT is the tangent and OP is the radius
so,
In triangle PTQ
