Line, Line Segment and Rays
Line, Line Segment and Rays are three fundamentals of geometry which forms the basis of almost every geometrical shape and figures. Let’s learn about their basic definitions and comparison between them.
- Line: A Line in mathematical geometry can be extended in both directions.
- Line Segment: A Line segment in mathematical geometry cannot be extended in any directions. It is represented by two fixed end points.
- Ray: A Line in mathematical geometry can be extended only in one direction.
Differences between Line, Line segment and Ray
The differences between Line, Line Segment and Ray is tabulated below:
Line | Line Segment | Ray |
|---|---|---|
Line has as no endpoint. | Line segment has two endpoints. | Ray has one endpoint. |
Both sides can be infinitely extended. | No side of line segment can be extended. | One side of a ray can be infinitely extended. |
A line is represented by arrows on both sides. | A line segment is represented by two fixed points on both sides. | A ray is represented by an arrow on one side and fixed point on one side. |

Ray in Geometry
Rays in mathematics are part of Geometry that has one side fixed and the other can be infinitely extended. In geometry, a ray is a line that starts at a single point, known as the endpoint and stretches infinitely in one direction. A real-world example of a ray is a beam of sunlight; the sun serves as the endpoint, and the light travels outward without end.
The representation of Ray is different from the other representations of line and line segments and holds a special significance for its unique properties.
In this article, we will discuss the real meaning of ‘Rays’ in geometry followed by ray properties, representation, real-life examples, and differences between rays and other representations like line and line segments. At the end of this blog, we will also look at some solved examples and practice problems on rays in geometry.
