C. They lie in the same plane
D. They are collinear
A set of 3 points will always be coplanar, but will only sometimes be collinear. Collinear points are always coplanar as well.
Parallel lines are ALWAYS coplanar.
Three coplanar points are always collinear if they lie on a single straight line. However, if they do not lie on the same straight line, they are not collinear. Thus, coplanar points can be either collinear or non-collinear, but they cannot be sometimes collinear; the relationship is definitive based on their arrangement.
Yes, two points are always collinear. You can draw a line through any two points.

Yes.

No but they are always coplanar.
Parallel lines are ALWAYS coplanar.
Yes, two points are always collinear. You can draw a line through any two points.
always
2 points determine a straight line and are always, by definition, collinear.
true
"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.
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.
Only when they are not collinear.
