Frequently Asked Questions
What is Euclidean distance?
Euclidean distance is the "straight-line" distance between two points — the length of the line segment connecting them. In 2D: d = √((x₂−x₁)² + (y₂−y₁)²). This is derived directly from the Pythagorean theorem.
What is Manhattan distance?
Manhattan distance = |x₂−x₁| + |y₂−y₁|. It measures distance as if you can only travel in axis-aligned directions (like city blocks). It is also called taxicab or L1 distance.
