As Class $IX\ C'$ s teacher Mrs.Rashmi entered in the class, She told students to do some practice on circle chapter. She Draws two-line $AB$ and $BC$ so that $AB = 8\ cm$ and $BC = 6\ cm.$ She told all students To make this shape in their notebook and draw a circle passing through the three points $A, B$ and $C.$
$i.$ Dileep drew $AB$ and $BC$ as per the figure
$ii.$ He drew perpendicular bisectors $OP$ and $OQ$ of the line $AB$ and $BC.$
$ii. OP$ and $OQ$ intersect at $O$
$iv.$ Now taking $O$ as centre and $OB$ as radius he drew The circle which passes through $A, B$ and $C.$
$v.$ He noticed that $A, O$ and $C$ are collinear.
