Line Segment
A portion of a line with two endpoints
A line segment is a part of a line that consists of two endpoints and all the points in between those two endpoints. It is the shortest distance between those two points. Unlike a line, which extends infinitely in both directions, a line segment has a definite measurable length.
The two endpoints of a line segment can be represented as points on a coordinate plane or described using words. When describing a line segment using words, it is common to label the two endpoints with capital letters, such as point A and point B. The length of the line segment can be found by measuring the distance between the two endpoints using a ruler or by using the distance formula in coordinate geometry.
Line segments are used in various fields such as mathematics, physics, engineering, and architecture. They can be used to represent physical objects or to measure distances between two points. For example, in architecture, line segments are used to determine the length of walls, doors, and windows, while in physics, they are used to calculate the distance traveled by an object along a straight line.
