Ray and Angles
Angles are formed from rays in geometry. An angle is formed when two rays combine with their fixed endpoints overlapping and the other infinitely extended side of ray then represent the arm of an angle.
Angle is the bent produced or the region between the two rays when they meet. In mathematics terms, the two rays that meet to form angle are called Arms of the Angle. One should note that the arms of angle are rays hence they can be extended individually in their defined direction and the extension of arms of angle doesn’t affect the value of the angle.
In the above figure represents ‘O’ as the fixed endpoint of two rays and OB and OA as the two individual rays making together an angle.

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.
