Question

what is the main difference between a line segment and a ray?
a line segment extends infinitely in one direction, while a ray does not.
a ray has two endpoints, while a line segment has one endpoint.
a line segment has two endpoints, while a ray has only one endpoint and extends infinitely in one direction.
a line segment and a ray both have no endpoints.

Explanation:

A line segment is a finite part of a line defined by two distinct endpoints, so it has a fixed length. A ray starts at one endpoint and extends infinitely in a single direction, with only one defined endpoint. We match these definitions to the options.

Answer:

C. A line segment has two endpoints, while a ray has only one endpoint and extends infinitely in one direction.
