Draw two tangents to a circle of radius 3.5 cm, from a point P at a distance of 6.2 cm from its centre.

Construction:

1) Construct a circle of radius AB = 3.5 cm.

2) Make a point P at a distance of OP = 6.2 cm, and join OP.

3) Draw a perpendicular bisector of OP.

4) Taking Q as centre and radius OQ = PQ, draw a circle to intersect the given circle at X and Y.

5) Join PX and PY to obtain the required tangents.

6) Thus, PX and PY are the required tangents.
