In geometry, a point is a specific location in space with no dimensions, represented by a dot. A line is a straight one-dimensional figure that extends infinitely in both directions, defined by at least two points. A plane is a flat, two-dimensional surface that extends infinitely in all directions, defined by three non-collinear points. Together, these three concepts form the foundational elements of geometric understanding.
When a line intersects a plane and does not lie in the plane, the intersection forms a single point. This point is where the line crosses the plane. If the line is parallel to the plane, however, there will be no intersection point.

The intersection of a line and a plane can result in either a single point, if the line passes through the plane, or no intersection at all if the line is parallel to the plane and does not touch it. In some cases, if the line lies entirely within the plane, every point on the line will be an intersection point. Thus, the nature of the intersection depends on the relative positions of the line and the plane.
When the line is inclined to the plane. That is, it is not in the plane nor is it parallel to it.
Plane. A point has no dimension, a line has one dimension, and a plane has two dimensions.

A plane intersects a line at a point, and i plane intersects another plane at a line.

When the line is inclined to the plane. That is, it is not in the plane nor is it parallel to it.
Unless the line is a subset of the plane, the intersection is a point.
