Line
In mathematics, a line is a one-dimensional geometric figure that extends infinitely in opposite directions
In mathematics, a line is a one-dimensional geometric figure that extends infinitely in opposite directions. It is often denoted by a straight, thin path with arrows on both ends to indicate its infinite nature. A line is composed of an infinite number of points that are equidistant from each other.
Lines have several key characteristics:
1. Straightness: Lines are perfectly straight and have no curves or bends.
2. Length: Lines have no endpoints and extend infinitely in both directions.
3. Angle: Lines have no width or thickness, which means they have zero degrees of angle.
4. Intersection: Two lines may intersect at a single point, forming an angle, or they can be parallel and never intersect.
Lines are fundamental in geometry and serve as the basis for various concepts and calculations. They are commonly used to represent paths, rays, and line segments. Lines are also utilized in linear equations to describe relationships between variables and in vector analysis to represent motion and direction.
