How it works
Distance = √((x₂ − x₁)² + (y₂ − y₁)²) — the straight line between two points.
Worked example
(0,0) to (3,4). = 5.
Frequently asked questions
Does this work in 3D?
This is the 2D straight-line distance. For 3D, add the z term: √(Δx² + Δy² + Δz²).
How does it relate to Pythagoras?
It IS Pythagoras — the distance is the hypotenuse of the right triangle formed by the x and y differences.
