Midpoint Calculator

The midpoint averages x's and y's separately: ((x₁+x₂)/2, (y₁+y₂)/2). It's the center of the segment — equidistant from both endpoints — and generalizes to 3D by averaging z too, or to any weighted split for points partway along.

Midpoints find circle centers from a diameter's endpoints, bisect map routes, center UI elements between anchors, and seed divide-and-conquer algorithms. Perpendicular bisectors — through the midpoint at right angles — construct circumcircles and Voronoi boundaries.
