Question

a line segment is defined as:
a. a part of a line that is bounded by two distinct end points
b. the longest distance between two points
c. a curved segment between two points
d. a path that connects any two points and extends infinitely in both directions

Explanation:

A line segment is a part of a line. It has two distinct endpoints. Option b is incorrect as the shortest distance between two points is a line segment (by the line - segment postulate in geometry). Option c is wrong because a line segment is straight. Option d describes a line (which extends infinitely in both directions), not a line segment.

Answer:

A. A part of a line that is bounded by two distinct end points
