No but they are always coplanar.
no.
Yes.
because coplanar is coplanar and collinear is collinear!!
Yes, collinear points are also coplanar.
Any set of points that are collinear must be coplanar.
Not sure about complanar. Coplanar lines can be collinear but need not be.
3 coplanar points may or may not be collinear. 3 collinear points must be coplanar.
A set of 3 points will always be coplanar, but will only sometimes be collinear. Collinear points are always coplanar as well.
True.
Collinear points are points that lie on the same line, while coplanar points are points that lie on the same plane.
Not necessarily. Coplanar means that points lie on the same plane whereas collinear means that points lie on the same line. Points on a plane do not necessarily lie along the same line.
