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.
