Final answer:
A ray in mathematics represents a set of points extending infinitely in opposite directions. It is a fundamental concept in geometry and is represented by a straight line originating from a point.
Explanation:
Ray is the term in mathematics that represents a set of points extending in opposite directions without ending. It is a straight line that originates at a specific point and extends indefinitely in one direction.
For example, in geometry, a ray is represented by an arrow pointing in one direction and continuing indefinitely in the opposite direction without any endpoint.
The concept of ray in mathematics is crucial for understanding geometric shapes, angles, and lines in various mathematical problems and applications.
