Collinear points are those points that lie on the same straight line. It is not necessary that they should be co-planar but they must lie on the same straight line. The word collinear is derived from the Latin words 'col' and 'linear' where 'col' stands for together and 'linear' means in the same line. The property of the points being collinear is known as collinearity. Let us learn more about collinear points in this article. Collinear points are a set of three or more points that exist on the same straight line. Collinear points may exist on different planes but not on different lines. The property of points being collinear is known as collinearity. So any three points or more will only be collinear if they are in the same straight line.

Mathematicians use words very exactly. 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. Linear means line.
