Theorem:If two tangents are drawn to a circle from an external point ; then (i) they subtend equal angles at the centre. (ii) they are equally inclined to the line segments ; joining the centre to that point.

If two tangents are drawn to a circle from an external point,then (i) they are equal (ii) they subtends equal angles at the centre.(iii) they are equally inclined to the segment; joining the centre to that point.

The tangents drawn from an external point to a circle (i) are equal, (ii) subtend equal angles at the centre.

Prove that the tangents drawn to a circle from an external point are equal.

Prove that the tangents drawn to a circle from an external point are equal.

Assertion(A) If two tangents are drawn to a circle from an external point then they subtend equal angles at the centre. Reason (R ) A parallelogram circumscribing a circle is a rhombus

The length of the two tangent segment drawn to a circle from an external point are……………..

The length of the two tangent segment drawn to a circle from an external point are……………..

Theorem : If two tangents are drawn to a circle from an external point are equal. Use Pythagoras theorem to write a proof of the above theorem.
