In mathematics, a ray is a geometric object that extends infinitely in one direction from a specific point called the endpoint

In mathematics, a ray is a geometric object that extends infinitely in one direction from a specific point called the endpoint. A ray can be thought of as a part of a straight line that starts at the endpoint and continues indefinitely in the other direction. It is typically denoted by placing an arrowhead at the endpoint.

A ray can be classified as either a half-line or a one-sided segment. A half-line has no endpoint on the side opposite the endpoint, while a one-sided segment does have an endpoint on the other side. However, both extend infinitely in one direction.

Mathematically, we can use symbols to represent a ray. For example, if point A is the endpoint of a ray, and we want to name the ray, we can use the symbol ⃗AB, where AB indicates the direction in which the ray extends.

Rays are often used in geometry and graphing to describe lines, angles, and other shapes. They help define and measure angles, as well as determine the direction and position of objects. Rays also play an essential role in vector mathematics and are used to represent vectors.

To summarize, a ray is a part of a straight line that starts at a specific point (endpoint) and extends infinitely in one direction. It is a fundamental concept in geometry and provides a way to describe and analyze mathematical shapes and objects.
