Question
Using a ruler, check whether the following points given in collinear or not:
$i.\ D, A$ and $C$
$ii.\ A, B$ and $C$
$iii.\ A, B$ and $E$
$iv.\ B, C$ and $E$
$i.\ D, A$ and $C$
$ii.\ A, B$ and $C$
$iii.\ A, B$ and $E$
$iv.\ B, C$ and $E$
✓
Answer
$i.\ D, A$ and $C$ are collinear points.
$ii.\ A, B$ and $C$ are non$-$collinear points.
$iii.\ A, B$ and $E$ are collinear points.
$iv.\ B, C$ and $E$ are non$-$collinear points.
$ii.\ A, B$ and $C$ are non$-$collinear points.
$iii.\ A, B$ and $E$ are collinear points.
$iv.\ B, C$ and $E$ are non$-$collinear points.
