What is Ray in Geometry?
Ray in Geometry is a special type of representation that can be infinitely extended from one side while the other side is static and represented by a single endpoint.
Ray can thus be considered as a one-side infinitely extended geometrical representation. In this blog, we have described ‘Ray in geometry’ in a detailed manner.
Ray in Mathematics Definition
Ray in Mathematics is any line that has a fixed endpoint on one side and on the other side, it can be extended infinitely.
The fixed endpoint is depicted by a point whereas the infinitely extandible side has an arrow on it.
Ray Notation
As ray only extends infinitely in one direction. To name a ray, say the name of the endpoint and any other point on the ray. The symbol for ray is →.
For example, if a ray has endpoint A, and B is any other point on the half-line, then the ray will be denoted by [Tex]\overrightarrow{AB}[/Tex]
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.
