……….tangent can be drawn from a point inside a circle .

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.

The number of tangents that can be drawn to a circle at any point on it is

The circle to which two tangents can be drawn from origin is

Calculate the length of tangent from a point 15 cm away from the centre of a circle of radius 9 cm .

The length of the tangent drawn from a point 17 cm away from the centre of a circle of radius 8 cm is

The length of the tangent from the point (-1,1) to the circle x^(2)+y^(2)-4x+k=0 equal to 2 then k=

A point P is 25 cm from the centre O of the circle. The length of the tangent drawn from P to the circle is 24 cm. Find the radius of the circle.
