Line Segment
A line segment is a part of a line that is bounded by two distinct end points. It is a straight path that extends from one point to another.
Key characteristics of a line segment:
- It has a definite length.
- It has two end points that mark its boundaries.
- It is a straight path with no curves or bends.
Notation: A line segment is often denoted by drawing a line over its two end points. For example, a line segment with end points A and B can be denoted as AB.
Examples of line segments can be found in everyday objects, such as the edge of a book, the side of a table, or the boundary of a piece of paper.
It's important to distinguish between a line segment and a line. A line extends indefinitely in both directions, while a line segment is a finite portion of a line.
