Steps of construction:
Construct a circle of radius 4 cm.
P is a point 7 cm away from the centre of the circle. Join OP.
Draw perpendicular bisector of OP which intersects OP at M.
Taking M as centre and OM as radius draw a circle which intersects the circle
C₁ at A and B.
Join PA and PB.
On measuring, we find,
PA = PB = 7.7 cm
Hence PA and PB are required tangents.
