The length of a line segment, denoted as “l,” refers to the distance between two distinct endpoints along a straight or curved line. In geometry, a line segment is a finite portion of a line with two endpoints. It represents a distinct and measurable portion of the line between two specific points. The concept of a line segment is fundamental in geometry and serves as a building block for more complex shapes and structures. It has properties such as length, which quantifies how long the segment is, and it can be used to measure distances or describe spatial relationships.
- l: Length of the line segment
- h: Perpendicular distance from point P to the vortex filament
- 𝜃: Angle between the line connecting point P to the filament and the direction perpendicular to the filament
