Plane-Line Postulate
If two points lie in a plane, then the line containing them lies in the plane
The Plane-Line Postulate is a fundamental concept in geometry that provides a way to establish the intersection between a plane and a line. According to this postulate, a line and a plane can either intersect in a single point or not intersect at all.
In case the line and the plane intersect in a single point, that point lies on both the line and the plane. This point is the common point of both the line and the plane that establishes the intersection.
On the other hand, if the line and the plane do not intersect, they are said to be parallel. This means that the line and the plane lie in the same direction, and do not have any common points.
The Plane-Line Postulate plays a significant role in various branches of geometry, including analytic geometry, projective geometry, and differential geometry. It provides a powerful tool for analyzing the intersection of lines and planes and is widely used in various applications, such as computer graphics, engineering, and architecture.
