Draw $\odot(O, 4\, cm)$ and a diameter $\overline{PQ}$ in it. Take points $A$ and $B$ such that $A-P-Q$ and $P-Q-B$. From $A$ and $B$,draw tangents to $\odot(O, 4\, cm)$. Write the steps of construction.

(N/A) Steps of construction:
$1$. Draw a circle with center $O$ and radius $4\, cm$.
$2$. Draw a diameter $\overline{PQ}$ passing through the center $O$.
$3$. Extend the diameter $\overline{PQ}$ on both sides to locate points $A$ and $B$ such that $A-P-Q$ and $P-Q-B$. Let $OA = OB = 6\, cm$ (or any distance greater than the radius).
$4$. Find the midpoints of $\overline{OA}$ and $\overline{OB}$ by constructing perpendicular bisectors. Let these midpoints be $M_1$ and $M_2$ respectively.
$5$. With $M_1$ as center and $M_1O$ as radius,draw a circle. It intersects the original circle at two points. Join $A$ to these points to get the tangents from $A$.
$6$. Similarly,with $M_2$ as center and $M_2O$ as radius,draw a circle. It intersects the original circle at two points. Join $B$ to these points to get the tangents from $B$.
