What is the distance formula?

The distance between two points is √((x₂ − x₁)² + (y₂ − y₁)²). It comes from the Pythagorean theorem applied to the horizontal and vertical gaps between the points.

Does this work for negative coordinates?

Yes. The differences are squared before the square root, so negative coordinates and any order of points give the same correct positive distance.

Distance between two points

The straight-line (Euclidean) distance between two points is found with the distance formula, which is the Pythagorean theorem applied to the gaps in x and y:

distance = √((x₂ − x₁)² + (y₂ − y₁)²)

The horizontal difference and vertical difference form the two legs of a right triangle, and the distance is the hypotenuse. Because the differences are squared, the order of the points and any negative coordinates do not change the result. Everything is computed in your browser.
