Question

draw a circle of 5cm radius.draw a diameter PQ.take three points R,SandT on the circle.draw<PRQ,<PSQand<PTQ.Measure each one of them with a protractor and write your observations.
​

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.
