Only when they are not collinear.
No but they are always coplanar.
No, they always are From Wikipedia.org, "The World's Encyclopedia" when I searched coplanar In geometry, a set of points in space is coplanar if the points all lie in the same geometric plane. For example, three distinct points are always coplanar; but four points in space are usually not coplanar. Since 3 points are always coplanar. A point and line are always coplanar
all of them are collinear they lie in the same plane
Yes. Any two points are always coplanar.
A set of 3 points will always be coplanar, but will only sometimes be collinear. Collinear points are always coplanar as well.
No. In order to be coplanar, points have to be in the line.
Three points are, but not four.
true
Definition of Coplanar points: Coplanar means that the points are on the equal plane. Plane is a two-dimensional object, with as such is a bit more complicated.Collinear,line,plane and point are the related terms of coplanar.Points that are on the same plane. 2 points are alwayscoplanar...3 points are always coplanar...4 points are sometimes coplanar.
YES!
This is a nonsense question. Any three point are always coplanar.
If they lie in the same plane.
