Geometry
The distance calculator finds the straight-line distance between two points using the distance formula. It works in both 2D and 3D coordinate space and also computes the midpoint.
In 2D: d = sqrt((x2-x1) squared + (y2-y1) squared). In 3D, add the z-component: d = sqrt((x2-x1) squared + (y2-y1) squared + (z2-z1) squared).
The midpoint is the average of the coordinates: ((x1+x2)/2, (y1+y2)/2) in 2D, with the z-average added for 3D.
d = sqrt((x2-x1)^2 + (y2-y1)^2)
Euclidean distance in 2D.
This calculator computes straight-line (Euclidean) distance only. It does not account for paths, roads, or curved surfaces.

5 units. This is the classic 3-4-5 right triangle: sqrt(9+16) = sqrt(25) = 5.
No. Distance is symmetric: the distance from A to B equals the distance from B to A.
