Line segment
A line segment is a part of a line that is bounded by two distinct endpoints. It contains every point on the line between its endpoints. In geometry, a line segment is often denoted by its endpoints, for example, the line segment with endpoints A and B is denoted as \(\overline{AB}\).
Properties[edit | edit source]
A line segment has several important properties:
- **Length**: The distance between its two endpoints. This can be measured using the distance formula in a coordinate system.
- **Midpoint**: The point that divides the segment into two equal parts. The midpoint can be found using the midpoint formula.
- **Collinearity**: Any point on the line segment is collinear with the endpoints.
Types of Line Segments[edit | edit source]
Line segments can be classified based on their relative positions:
- **Horizontal Line Segment**: A line segment that runs from left to right or right to left.
- **Vertical Line Segment**: A line segment that runs up and down.
- **Oblique Line Segment**: A line segment that is neither horizontal nor vertical.
Applications[edit | edit source]
Line segments are fundamental in various fields of mathematics and engineering:
- In geometry, they are used to construct shapes and figures.
- In computer graphics, line segments are used to draw shapes and models.
- In physics, they can represent vectors and forces.
