Two tangents PQ and PR are drawn from an external point to a circle with centre O . Prove that QORP is cyclic quadrilateral.

Two tangents P Aa n dP B are drawn from an external point P to a circle with centre Odot Prove that A O B P is a cyclic quadrilateral.

Two tangents P Aa n dP B are drawn from an external point P to a circle with centre Odot Prove that A O B P is a cyclic quadrilateral.

If the points of contact of the tangents drawn from an external points P to a circle with centre O be A and B,then show that PAOB is a cyclic quadrilateral.

two tangents RQ and RP are drawn from an external point R to the circle with centre O. If /_PRQ =120^@ , then prove that OR= PR+ RQ

two tangents RQ and RP are drawn from an external point R to the circle with centre O.If /_PRQ=120^(@), then prove that OR=PR+RQ

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

In Fig. two tangents RQ and RP are drawn from an external point R to the circle with centre O. If anglePRQ = 120 ^@ , then prove that OR = PR + RQ .

AP and AQ are two tangents drawn from an external point A to a circle with centre O, P and Q are points of contact. If PR is a diameter, prove that OA||RQ.
