Point C lies between points A and B on AB above. Collinear points are points that lie on the same line. In Euclidean geometry Collinear points are points that all lie in the same line whether they are close together far apart or form a ray line segment or line.
Collinear points are the set of points that lies on the same straight line.
Any two points are collinear because any two points determine a line. In Euclidean geometry Collinear points are points that all lie in the same line whether they are close together far apart or form a ray line segment or line. Point C lies between points A and B on AB above. Obviously two points are always collinear since a straight line can always be drawn through two points.
