Question

Draw a circle of diameter $9cm$. Mark a point at a distance of $7.5cm$ from the centre of the circle. Draw tangents to the given circle from this exterior point. Measure the length of each tangent.

Answer 1

I. Draw a circle of diameter $9$cm, taking O as centre.

II. Mark a point P outside the circle, such that PO$=7.5$cm

III. Taking OP as the diameter, draw a circle such that it cuts the earlier circle at A & B

IV. Join PA & PB.

PA & PB are tangents.
