1.) Points A, F, G are collinear to line l. Collinear means that a point lies exactly on a line.
2.) Two points non collinear to points B and A: points C and D are non collinear to points B and A. Non collinear means that a points or a set of points do not lie on a certain line, but they lie outside or away from the line.
