No. A trinagle does not require four points, three are sufficient. And any three points, if they are not colinear, must be coplanar.
YES!
They lie in the same plane, but they don't necessarily have to lie on the same line. Every triangle consists of three points that are coplanar but non-colinear.
Coplanar Points are points that lie on the same line.
True.
Three balls on a table are three coplanar points.
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
In 3-dimensional space, yes, any three points are coplanar.
No. A trinagle does not require four points, three are sufficient. And any three points, if they are not colinear, must be coplanar.
No but they are always coplanar.
This is a nonsense question. Any three point are always coplanar.
Three points are, but not four.
no.
Yes.
Yes.
Individual points on one side of the cube are coplanar. Points on one side might not nessasarily be coplanar with points on another side. The corners of a cube are exactly coplanar to three planes, but not all planes of the cube. In fact, no point on the cube is coplanar to all other points on the cube.
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.
