Definition

A ray is a part of a line that starts at a point and extends infinitely in one direction.

Description

A ray is fundamental in geometry as it helps define angles and directions. For example, the sun's rays illustrate this concept by starting at the sun and extending outward infinitely. Understanding rays is essential for studying other geometric shapes and their properties, such as angles formed by intersecting rays. This concept is widely used in fields like physics and engineering to represent light and other directional phenomena.
