Circles|Pair of tangents from outside the circle

Tangents from a Point Outside the circle.

Draw a circle with the help of a bangle. Take a point outside the circle. Construct the pair of tangents from this point to the circle.

The pair of tangents from origin to the circle x^(2)+y^(2)+4x+2y+3=0 is

The pair of tangents from (2,1) to the circle x^(2)+y^(2)=4 is

Number of tangents drawn from a point inside the circle is :

Maximum number of tangents drawn from a point on the circle is :

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