(1)Draw two concentric circle C

1

and C

2

with common center

0 and radius 4cm and 6cm

(2) Take a point P on the outer circle C

2

and join OP.

(3) Draw the bisector of OP which bisect OP at M'.

(4) Taking M' as center and OM' as radius draw a dotted circle which

cut the inner circle C

1

at two point M and P.

(5) Join PM and PP'. Thus, PM and PP' are required tangent.

On measuring PM and PP'.

PM=PP

=4.4cm

Bycalculation:

InΔOMP,∠PMO=90

PM

=20cm

PM=

=4.4cm

Hence,
