Points, Lines, Line Segments, & Rays

A point is a specific location in space that has no size or dimension.

A line is straight and extends in both directions forever.

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

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

Parallel lines are lines in a plane that never meet and are always the same distance apart.

A line segment is named by its two endpoints, for example, segment AB.

A ray is named by its starting point and another point on the ray, for example, ray AB.

A line extends infinitely in both directions, while a line segment has two endpoints.

A ray has one endpoint and extends infinitely in one direction, while a line segment has two endpoints.

Intersecting lines are lines that cross each other at one point.
