What formula does this use?

The distance formula d = √((x₂−x₁)² + (y₂−y₁)²), derived directly from the Pythagorean theorem by treating the horizontal and vertical differences between the two points as the two legs of a right triangle.

Does this work in 3D?

No — this calculates distance on a flat 2D plane only, using just x and y coordinates. A 3D version adds a z-coordinate and an extra squared term under the same square root: d = √((x₂−x₁)² + (y₂−y₁)² + (z₂−z₁)²).

What is the midpoint, and how is it different from the distance?

The midpoint is the single point exactly halfway between your two coordinates, found by averaging the x-values and averaging the y-values separately. Distance tells you how far apart the points are; midpoint tells you where the center between them sits.

Can I use negative coordinates?

Yes — the formula works correctly regardless of sign, since each difference is squared before being added, which makes the result positive either way. Negative coordinates simply place a point in a different quadrant of the plane.

Does the order of the two points matter?

No — swapping which point is "first" and which is "second" flips the sign of each difference before squaring, and squaring removes the sign, so the distance comes out identical either way.
