Questions Fréquemment Posées — Midpoint Calculator
What is the midpoint formula?
The midpoint M between (x₁,y₁) and (x₂,y₂) is M = ((x₁+x₂)/2, (y₁+y₂)/2). For 3D points: M = ((x₁+x₂)/2, (y₁+y₂)/2, (z₁+z₂)/2). The midpoint is exactly halfway between the two points.
How do I find a missing endpoint from the midpoint?
If you know one endpoint (x₁,y₁) and the midpoint M(mx,my), find the other endpoint: x₂ = 2·mx − x₁, y₂ = 2·my − y₁. Example: endpoint (2,3), midpoint (5,7) → other endpoint = (2·5−2, 2·7−3) = (8,11).
When is the midpoint formula used?
The midpoint formula is used in geometry (bisecting line segments, finding centers of shapes), computer graphics (drawing between pixels), navigation (finding halfway points), and physics (center of mass for equal masses). It's also used in the midpoint method for numerical integration.
