Question

Draw two concentric circles of radii 2cm and 5cm. Take a point p on the outer circle and construct a pair of tangents pa and pb to the smaller circle. Measure pa. ​

Answer 1

Step-by-step explanation:

Draw a circle of radius 5 CM and 2 cm

Take a point p on outer circle and join op

Bisect op

Draw a circle taking op as diameter

join ap, bp, oa and ob

Answer 2

Given:

We have two concemtric circle of radius 2cm.

To Find:

We need to draw a tangent to smaller circle?

Step-by-step explanation:

• First of all draw a circle of raidus 2cm with centre O.

• Now draw another circle with same centre O of radius 5cm.

• Now take a point P on circumference of larger circle.

• Bisect OP. Let M be the mid-point of OP.

• Taking M as its centre and MO as its radius ,Draw a circle.let it intersect the given circle at the points A , B .

• Join PA and PB .

• PA and PB are the required tangents.
