Answer
Steps of Construction :
Draw a circle with center O and radius 3 cm.
From O, take a point P such that OP = 5 cm.
Draw a perpendicular bisector of OP which intersects OP at M.
With center M and radius OM, draw a circle which intersects the circle with center O at A and B.
Join AP and BP. Measure AP and BP.
Hence, AP and BP are required tangents.
On measuring,
AP = BP = 4 cm.
Hence, length of each tangent = 4 cm.
