A line segment is a part of a line that is bounded by two distinct endpoints
A line segment is a part of a line that is bounded by two distinct endpoints. It can be thought of as a straight path between two points. A line segment is finite in length and has no thickness or width. It can be measured using units such as inches, centimeters, or any other unit of length.
The two endpoints of a line segment are usually labeled with capital letters. For example, if we have a line segment from point A to point B, we can denote it as AB. The order of the endpoints is important, as it specifies the direction of the line.
A line segment can be described in terms of its length. To find the length of a line segment, you can measure the distance between its endpoints using a ruler or by using the distance formula in coordinate geometry. The length is always a positive value and is the same irrespective of the orientation of the segment.
It is worth noting that a line segment differs from a line, which extends indefinitely in both directions, and from a ray, which extends infinitely in one direction from an initial point. Line segments are commonly encountered in geometry, trigonometry, and other branches of mathematics and are often used to represent distances, intervals, or positions.
