Equation Of Tangent To Circle

For the construction of a tangent to a circle without using its centre, the property used is

Construct a pair of tangents to a circle of radius 3 cm which are inclined to each other at an angle of 60^(@)

Common Tangents of Circles

Draw a circle of radius 3 cm. Take a point P at a distance of 5 cm from the centre of the circle. From P, construct a pair of tangents to the circle.

Draw a circle of radius 3.5 cm. Take a point P outside the circle at a distance of 7 cm from the centre of the circle and construct a pair of tangents to the circle from the point.

To construct the tangents to a circle from a point outside it.
