In geometry, a line segment is bounded by two distinct points on a line. Or we can say a line segment is part of the line that connects two points. A line has no endpoints and extends infinitely in both the direction but a line segment has two fixed or definite endpoints.

A segment is named by its two endpoints, for example, ¯AB . A ray is a part of a line that has one endpoint and goes on infinitely in only one direction. You cannot measure the length of a ray. A ray is named using its endpoint first, and then any other point on the ray (for example, →BA ).

Which figure goes on forever in only one direction?

A ray has one endpoint and goes on forever in one direction. Mathematicians name a ray with notation like , where point E is the endpoint and F is a point on the ray.

A point is a single, precise location, describable in a single coordinate pair. A segment runs between two points. A ray starts at a point and goes forever in a specific direction. A line runs forever in both directions.

A line is a one-dimensional figure, which has length but no width. A line is made of a set of points which is extended in opposite directions infinitely. It is determined by two points in a two-dimensional plane. The two points which lie on the same line are said to be collinear points.

A (straight) line has length but no width or thickness. A line is understood to extend indefinitely to both sides. It does not have a beginning or end. A line consists of infinitely many points.
