Two points are collinear if there is a line going through them. A higher-dimensional counterpart to this is "coplanar": objects are coplanar if there is a plane that contains the objects. There's always a plane containing any three points, so you'd need at least four points (in at least three dimensions) for this distinction to be meaningful. However, it's also possible to discuss two or more coplanar lines, for example - if two lines are not coplanar, they are called skew. To visualize this, imagine a bridge crossing a river: the bridge and the river could be extended into lines that are not contained in any common plane. Beyond coplanar objects, it's possible to discuss "cospatial" objects that lie in the same three-dimensional space. However, you'd need at least four dimensions to even talk about this, since in three dimensions everything is cospatial, in a way. Another related concept to collinear is "concurrent." This refers to three or more lines (or circles) that all intersect at the same point.

What does it mean for two points to be collinear?
"Collinear" means "on the same straight line".Two points are always collinear, because you can always draw a straight linebetween any two points. Three points may or may not be collinear.
Which of these applies to form one dimensional two dimensional or three dimensional?
three dimensional
Is a penny two or three dimensional?
three dimensional
What is the difference between collinear and non collinear?
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.
Are three points always collinear?
No but they are always coplanar.
What are two or three points if they lie on the same line?
They are said to be collinear.

A map, painting, or photograph, are all two dimensional representatins of three dimensional objects
How many line can contain 3 non collinear points?
Two intersecting lines can always cover three non-collinear points.
