Question

. a) How many tangents can be drawn from an exterior point to circle b. Draw a circle of radius 3 cm. Mark a point Pat a distance 7,5 cm away from the centre. Draw tangents from P to the circle, ​

Answer 1

Answer:

Steps of construction :

1.Take a point O as center and with radius 3 cm ,draw a circle.

2.Mark a point P outside the circle such that OP=5 cm.join O to P.

3.Draw a perpendicular bisector of OP that cuts OP at M.

4.With M as a center and radius MO (or MP),draw a circle cutting the first circle at A and B.

5.Join P to A and P to B

Then PA and PB are the required two tangents

The length of the tangent are PA=PB=4 cm.

Answer 2

Answer:

Two tangents

Step-by-step explanation:

Two tangents can be drawn from an exterior point to a circle
