Solved Examples on Rays
Below are some examples to help you understand about rays in geometry.
Example 1: Draw a ray of length 10 cm and label the fixed endpoint as P and point that can extended indefinItely as Q.
Example 2: Identify the fixed endpoint and point which can be infinitely extended for the below ray image.
Solution:
In the above image,
Point R is the fixed endpoint which is static and cannot be extended as it is represent by point.
Point S is the point which can be infinitely extended as it is represented by arrow.
Example 3: Identify the point which can be infinitely extended for the below ray image.
Solution:
In the above image, point B can be infinitely extended for the ray.
Example 4: Draw a ray of 5 cm and represent the fixed endpoint as S.
Solution:
Here, S is the fixed point, T is the point which can be extended infinitely and the ray length is 5 cm.
Example 5: Draw a ray of 7 cm and represent the fixed endpoint as Y and the infinitely extendible point as Z.
Solution:
Here, Y is the fixed point, Z is the point which can be extended infinitely and the ray length is 7 cm.
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.
