Given an arc of a circle,complete the circle.
(N/A) Let arc $PQ$ of a circle be given. We have to complete the circle,which means that we have to find its centre and radius.
$1$. Take a point $R$ on the arc $PQ$.
$2$. Join $PR$ and $RQ$ to form two chords $PR$ and $RQ$.
$3$. Draw the perpendicular bisectors of chords $PR$ and $RQ$.
$4$. The point where these two perpendicular bisectors intersect is the centre $O$ of the circle.
$5$. With $O$ as the centre and $OP$ (or $OQ$ or $OR$) as the radius,draw the circle to complete it.
