Points that lie on the same line
When two points lie on the same line are called collinear. When they lie on the same plane they are called coplanar.
Points that lie on the same plane are not necessarily collinear.
When points are collinear, they lie on the same plane. Then when points are collinear they are necessarily coplanar. But when they are coplanar they are not necessarily colinear.
This means that points that lie on the same line are collinear and coplanar too.
