[PQ" is a tangent to a circle with centre "O" ."],[P" is a point of contact.Then find "/_OPQ" ."]

PQ and RS are two parallel tangents to a circle with centre O and another tangent AB wih point of contact C intersect PQ at A and RS at B. then find angle AOB

PQ is a tangent to a circle with centre O at the point P. If OPQ is an isosceles triangle, then /_OQP is equal to 30o (b) 45o(c)600 (d) 90o

If two tangents are inclined at 60^(@) are drawn to a circle of radius 3cm then find length of each tangent. OR PQ is a tangent to a circle with centre O at point P. If Delta OPQ is an isosceles triangle, then find angle OQP.

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 ?

PQ is a tangent to a circle with centre O at the point P. If DeltaOPQ is an isosceles triangle, then angleOQP=………. .

PQ is a tangent to a circle with centre O at the point P . If DeltaOPQ is an isoceless triangle, then /_OQP is equal to

In figure, PQ is a tangent at a point R of the circle with centre O. If /_TRQ = 30° , find /_PRS .

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.

PQ is a tangent drawn from a point P to a circle with centre O and QOR is a diameter of the circle such that angle POR =120^(@) . Find angle OPQ .

PQ is a tangent drawn from a point P to a circle with centre O and QOR is a diameter of the circle such that /_POR=120o, then /_OPQ is 60o (b) 45o (c) 30o (d) 90o
