Question

which is the definition of a ray?
a part of a line that has one endpoint and extends indefinitely in one direction
the set of all points in a plane that are a given distance away from a given point
lines that lie in the same plane and do not intersect
a part of a line that has two endpoints

Explanation:

• Analyze each option:
• First option: A ray is defined as a part of a line with one endpoint and extending infinitely in one direction. This matches the definition of a ray.
• Second option: This defines a circle (set of points at a given distance from a center point).
• Third option: This defines parallel lines.
• Fourth option: This defines a line segment (part of a line with two endpoints).

Answer:

A. a part of a line that has one endpoint and extends indefinitely in one direction
