Question

1. a line segment is defined as:

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

Explanation:

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

Answer:

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