A point is a concept in Euclidean geometry without length or breadth or depth. A point is made up of no other parts. The extremities of a line are points. A line is made up of an infinite nimber of points. Any line can be completely defined by two distinct points. Any plane can be completely defined by three distinct points that are not all part of the same line. Any two lines that lay on a single plane and are not parallel will intersect at a single point. Any three planes such that no plane is parallel to either of the other two will intersect at a single point.
