Question

draw two tangents to a circle of diameter 8 cm from a point P at a distance of 4.2 cm from it centre​

Answer 1

Answer:

Steps of construction :

1. Draw a line segment OA=8 cm.

2.O as centre and radius 4 cm draw a circle.

3. Taking OA as diameter draw another circle which intersects the given circle at B and C.

4. Join A to B and A to C.

Result:AB and AC are required tangents.

∴AB=AC=5.9 cm.
