Question

Draw a circle of radius $4cm$ with centre $O.$ Draw a diameter $POQ.$ Through $P$ or $Q$ draw tangent to the circle.

Answer 1

We follow the following steps.

Steps of construction :
$STEPI$
Taking $O$ as centre and radius equal to $4cm$ draw a circle.

$STEPII$
Draw diameter of $POQ$.

$STEPIII$
Construct $\angle PQT={90}^o$

$STEPIV$
Produce $TQ$ to $T^{\prime }$ to obtain the required tangent $TQ{T}^{\prime }$.
