In 3-dimensional space, yes, any three points are coplanar.
Three balls on a table are three coplanar points.
Yes. Any two points are always coplanar.
No but they are always coplanar.
Yes.
No. For any three points it is always possible to find a plane on which they all lie. A fourth point is most unlikely to be coplanar with the first three unless it is deliberately placed to be so.
This is a nonsense question. Any three point are always coplanar.
No. A trinagle does not require four points, three are sufficient. And any three points, if they are not colinear, must be coplanar.
Three balls on a table are three coplanar points.
Yes. In fact, any three are.
Points that lie on the same plane are coplanar. Generally, three points have to be coplanar, but more than that can be in any plane.
Yes. Any two points are always coplanar.
No
No, a line cannot contain four non-coplanar points. By definition, coplanar points are points that lie in the same plane, and any three points determine a plane. Since a line consists of an infinite number of points that are linear, any additional point beyond two points on a line will not be able to create a non-coplanar arrangement with those already on the line. Thus, four points on a line must be coplanar.
Any set of points that are collinear must be coplanar.
No but they are always coplanar.
Three points are, but not four.
no.
