Not sure about complanar. Coplanar lines can be collinear but need not be.
no.
6*5/2 = 15.
5 its 4
exactly nine planes! * * * * * I would have said 4 - corresponding to the four faces of a tetrahedron. Of course, non-collinear does not mean non-coplanar so all four points could be in the same single plane!
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.
No but they are always coplanar.
Collinear points are points that lie on the same line, while coplanar points are points that lie on the same plane.
