Question

Draw a circle with centre $O$ and radius $4$ cm. Draw any diameter $AB$ of this circle. Construct tangents to the circle at each of the two end pointsd of the diameter $AB$.

Answer 1

Steps of construction:

1) Draw a circle with centre $O$ and radius $4$ cm.

2) Draw any diameter $AB$.

3) Draw line $L\perp OA$ such that $\angle OAL={90}^0$

4) Draw line $M\perp OB$ such that $\angle OBM={90}^0$

Thus, $LA$ and $LB$ are the required tangents.
