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.
