The number of points such that the tangents from it to three given circles are equal in length is

Tangents from a Point Outside the circle.

Locus of the point,the difference of the square of length of the tangents drawn from which to two given circle is constant is:

A point P is 13 cm from the centre of the circle. The two tangent PQ and PR are drawn from the point P, The length of the tangent drawn from P to the circle is 12 cm. Find the length of OR.

A point P is 13 cm from the centre of the circle. The two tangent PQ and PR are drawn from the point P, The length of the tangent drawn from P to the circle is 12 cm. Find the length of PR.

Length of tangent from a Point to a Circle.

A point P is 13 cm from the centre of the circle. The two tangent PQ and PR are drawn from the point P, The length of the tangent drawn from P to the circle is 12 cm. anglePQO is equal to ………. .

Prove that the locus of a point,which moves so that its distance from a fixed line is equal to the length of the tangent drawn from it to a given circle,is a parabola.

A point P is 13 cm from the centre of the circle. The two tangent PQ and PR are drawn from the point P, The length of the tangent drawn from P to the circle is 12 cm. Find the radius of the circle.
