Which term is defined as a part of a line with two endpoints?

• A. Segment
• B. Ray
• C. Line
• D. Point

Answer: (A)

A line segment is the finite part of a line bounded by two endpoints. It lies on the line and has a definite length because those endpoints fix its ends. In contrast, a line goes on forever in both directions, so it has no endpoints and no finite length. A ray starts at one endpoint and extends indefinitely in one direction, giving it one endpoint but infinite length in that direction. A point has no length at all—it's just a location. So the term that matches “a part of a line with two endpoints” is a line segment.
