Construct a tangent to a circle of radius 4cm from a point which is at a distance of 6cm from its center.


Given,


Point M’ is at a distance of 6 cm from the center of a circle of radius 4 cm.


Steps of construction


1. Draw a circle of radius 4 cm.


2. Join OM’ and bisect it. Let M be mid-point of OM’.


3. Taking M as center and MO as radius draw a circle to intersect circle (0,4) at two points P and Q.


4. Join PM’ and QM’. PM’ and QM’ are the required tangents from M’ to circle C (0,4).
