Points, Lines, Planes, Rays and Segments

A point is a specific location in space that has no dimensions, represented by a dot.

A line is a straight one-dimensional figure that extends infinitely in both directions, having no endpoints.

A plane is a flat two-dimensional surface that extends infinitely in all directions.

A ray is a part of a line that starts at a point and extends infinitely in one direction.

A line segment is a part of a line that has two endpoints.

Points are coplanar if they lie on the same plane.

The intersection of two lines is the point where they meet or cross each other.

The intersection of a line and a plane is the point where the line crosses the plane.

Noncoplanar points are points that do not lie on the same plane.
