[" 25.In the given fig."KN" ,PA and "PB" are tangents to the circle.Prove that: "],[KN=AK+BN" ."]

In the given figure, PA and PB are tangents to a circle with centre O. Prove that angleAPB and angleAOB are supplementary.

In the given figure, PA and PB are tangents to a circle with centre O. Prove that angleAPB and angleAOB are supplementary.

In the figure ,if PA and PB are tangents and AB=AP,then angleAPB is:

In the given figure PA and PB are tangents to the circle drawn from an external point P. CD is a third tangent touching the circle at Q. If PB=10cm and CQ=2cm. What is the length of PC?

In the given figure PA and PB are tangents to the circle drawn from an external point P. CD is a third tangent touching the circle at Q. If PB=10cm and CQ=2cm. What is the length of PC?

In the given figure, PA and PB are tangents to the circle from an external point P. CD is another tangent touching the circle at Q. If PA =12 cm, QC=3cm, then find PC+PD.

In the given figure, PA and PB are tangents to the circle from an external point P. CD is another tangent touching the circle at Q. If PA =12 cm, QC=3cm, then find PC+PD.

PA and PB are tangents to the circle with center O such that /_APB=50° , find /_OAB .

PA and PB are tangents to the circle with centre O such that /_APB = 60° , find /_OAB .
