Question

construct a tangent to a circle.
of radius 3cm from a point on
the concentric circle of radius 7cm
and meature ite length. Also verify
the measurement by actual calculation​

Answer 1

Answer:

ANSWER

(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
