Line Segment
A line segment is a part of a line that is bounded by two distinct endpoints. It is a straight path between two points, and it includes these points and all the points between them.

Characteristics of a Line Segment
- A line segment has a definite length, which can be measured using a ruler or a measuring tape.
- It is a finite portion of a line and does not extend indefinitely in either direction.
- The two endpoints of a line segment are always distinct points that mark the beginning and end of the segment.

Representation of Line Segments
Line segments can be represented by drawing a line between two points and marking it with a line segment symbol. The symbol looks like a line with a small line segment mark at each end.

Use of Line Segments
In geometry and mathematics, line segments are used to measure distances, define shapes, and solve problems related to length and position. They are essential elements in constructing geometric figures and understanding spatial relationships.

Example of Line Segment
In the story "Taro's Reward," a line segment can be visualized as the path Taro takes to reach the top of the mountain to claim his reward. The line segment starts at the base of the mountain, where Taro begins his journey, and ends at the summit, where he finds the reward waiting for him. This line segment represents the distance Taro travels and the goal he achieves.
