What this calculator does
The midpoint lies exactly halfway between two points. It is found by averaging the coordinates and works the same way in two and three dimensions.
Formula and method
M = ((x₁ + x₂)/2, (y₁ + y₂)/2, (z₁ + z₂)/2)
Worked example

Questions
How do I find an endpoint from a midpoint?
x₂ = 2Mx − x₁, and similarly for y and z.
