What it does
Computes √(Δx² + Δy²).
How to use it
Enter four coordinates, then calculate.
Formula
d = √((x₂−x₁)² + (y₂−y₁)²).
Example
(0,0) to (3,4) → distance 5.
FAQs
Does it work with negatives?
Yes; squaring removes sign issues.
3D distance?
Add Δz² under the square root; this page is 2D only.
Manhattan distance?
That is |Δx|+|Δy|; different metric from Euclidean.
