The classic straight-line (Euclidean) metric between two 2D points: √(dx² + dy²). The workhorse of geometry, graphics, and machine-learning k-NN.
Pythagorean straight-line distance between two 2D points.
d = √((x₂−x₁)² + (y₂−y₁)²)
| Symbol | Meaning |
|---|---|
| d | Euclidean (L²) distance |
(1,2)→(4,6): dx=3, dy=4, d = 5.
