A pair of perpendicular tangents are drawn to a circle from an external point. Prove that the length of each tangent is equal to the radius of the circle.

To draw a pair of tangents to a circle inclined to each other at 40^@ , the angle at the centre of the circle between the two radii is _______

Draw a circle a radius 6 cm. From a point 10 cm away from its centre, construct the pair of tangents to the circle and measure their lengths.

Draw a circle of radius 4 cm and construct a pair of tangents such that the angle between then is 60^@ .

How can you prove the converse of the above theorem. " If a line in the plane of a circle is perpendicular to the radius at its endpoint on the circle, then the line is tangent of the circle ".

If y=3 x is a tangent to a circle with centre (1,1) then the other tangent drawn through (0,0) to the circle is

A straight line passing through a point on a circle is
