Draw a circle of radius 3.5 cm. Take two points A and B on one of its extended diameter, each at a distance of 5 cm from its center. Draw tangents to the circle from each of these points A and B.

Steps of Construction:

1. Draw a circle of radius 3.5 cm.

2. Draw diameter of circle, and extend it and mark points P and Q, 7 cm from the center.

3. Make perpendicular bisector of OP. Let M be the midpoint of OP.

4. Taking M as center and OM as radius, draw a circle.

5. Let it intersect the given circle at points A and B.

6. Join PA and PB.

7. Similarly, we draw tangent from point Q.

Therefore, PA and PB are tangents from P and QC and QD are the tangents from Q.
