A line segment is a part of a line that is defined by two endpoints
A line segment is a part of a line that is defined by two endpoints. It is a straight path that connects these two points. The length of a line segment can be determined by measuring the distance between its endpoints.
In geometry, a line segment is often represented by drawing a straight line with a small line segment on top of it, indicating its length. For example, if the line segment is 4 units long, it can be denoted as AB = 4, where A and B are the endpoints.
Unlike a line, which extends infinitely in both directions, a line segment has a definite length and does not go on indefinitely. Therefore, it is a finite portion of a line. Additionally, a line segment cannot be extended beyond its endpoints.
Line segments are fundamental elements in geometry and are used to form various geometric shapes. They can be combined to create polygons, angles, and other geometric constructions. The concepts of midpoint, parallelism, and perpendicularity can also be defined using line segments.
It is important to note that a line segment is different from a ray. A line segment has two endpoints, while a ray has only one endpoint and extends infinitely in one direction.
