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.`

In the figure , PQ and PR are tangents drawn from and external point P to the circle with centre O. Q and R are the points of contact. If PQ = 5 cm then what is the length of segment PR ? Why ?

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 PQ and PR are drawn from an external point to a circle with centre 0. Prove that QORP is cyclic quadrileral.

AP and AQ are tangent drawn from a ponit A to a circle with centre O and radius 9cm. If OA = 15 cm. then AP + AQ = …….. Cm.

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

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 .

PR and PS are two tangents drawn from a extental point P of the Circle with centre at O. If PR =8 cm and angle RPO=60^(@), then the length of PS=

Two tangents PA and PB are drawn from an external point P to a circle with centre at O. If AOB = 105^(@) the A hat(P) B is :

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.

If from an external point P of a circle with centre O,two tangents PQ and PR are drrawn such /_QPR=120^(@), prove that 2PQ=PO .
