3 points must always be contained in one plane, as 2 make a line, it makes no difference as to where the third point is, it will exist in the same plane in the two. Aside from all three points being in a line, this is always true.

Non collinear refers to three or more points that are not all on the same straight line.

Typically, a line is named with two points on the line.

Two intersecting lines can always cover three non-collinear points.

In order for three or more points to be collinear, they must lie on the same line. Two points would always be collinear. Noncollinear are points that do not lie in the same line.

Points that are contained on the same line or portion of a line are considered to be collinear.

Is false

No, because Of any three points on a line there exists no more than one that lies between the other two.

if there are three or more points not all of which lie on the same line then they are known as non linear pointsif there are specifically three points not all of which lie on the same line then they are known as coplanar points as they will always lie on one plane

Circumcenter, Incenter and Centroid.

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

Is true

Collinear

Collinear points are points that lie on the same line. Noncollinear points do not lie on the same line. Any two points are always collinear, i.e. forming a line. Three or more points can be collinear along a single line.Collinear points lies on the same straight line.

Non collinear refers to three or more points that are not all on the same straight line.
