The lengths of the two tangents from an external point to a circle are equal.

If the length of the tangent from an external point P to a circle of radius 10cm. Is 24cm, then the distance of P from the centre is

Prove that the angle between the two tangents drawn from an external point to a circle is supplementary to the angle subtended by the line - segment joining the points of contact at the centre.

Prove that the internal bisector of the angle between two tangents drawn from an external point of a circle will pass through the centre of the circle.

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.

The chord of contact of tangents from a point P to a circle passes through Q. If l_1 and l_2 are the lengths of the tangents from P and Q to the circle ,then PQ is equal to

The lengths of the tangents from P(1,-1) and Q(3,3) to a circle are sqrt(2) and sqrt(6) , respectively. Then, find the length of the tangent from R(-1,-5) to the same circle.

Only three tangents can be drawn from a external point of a circle.

Write True or False: Two tangents can be drawn from any external point to a circle.

In the adjoining figure, two tangents drawn from external point C to a circle with centre O touches the circel at the point P and Q respectively. A tangent drawn at another point R of the circle intersects CP and CQ at the points A and B respectively. If CP = 7 cm and BC =11 cm, then determine the length of BR.

O is the centre of a circle. An external point P is 26 cm away from the centre of the circle and the length of the tangent (PT) drawn from the point P to the circle at T is 10 cm. Calculate the length of the diameter of the circle.
