Understanding Rays in Mathematics | Definition, Uses, and Symbol

Ray

In mathematics, a ray is a line with a fixed starting point called the endpoint, and it extends infinitely in one direction

In mathematics, a ray is a line with a fixed starting point called the endpoint, and it extends infinitely in one direction. The endpoint is often denoted as a small dot or a letter. Rays are named using the endpoint and a point on the ray, with the endpoint always being mentioned first.

A ray can also be described as a part of a line that starts at a specific point and goes on forever in one direction. It is important to note that a ray has no specific length since it extends infinitely.

Rays are commonly used in various mathematical concepts, such as geometry and trigonometry. For example, in geometry, rays can be used to define angles or determine the direction of lines or vectors. In trigonometry, rays are often used to represent angles in the coordinate plane.

The symbol used to represent a ray is an arrowhead pointing in the direction of the ray. This arrowhead indicates that the ray extends infinitely in that direction.

To summarize, a ray in mathematics is a line with a single endpoint that continues indefinitely in one direction. It is an important concept in geometry and trigonometry and is represented by an arrowhead pointing in the direction of the ray.
