The Distance Formula

2D Distance (Euclidean)

The distance between two points in a plane, derived from the Pythagorean theorem.

d = √[(x₂ - x₁)² + (y₂ - y₁)²]

3D Distance

Extended to three dimensions for points in space.

d = √[(x₂ - x₁)² + (y₂ - y₁)² + (z₂ - z₁)²]

Midpoint Formula

The point exactly halfway between two points.

M = ((x₁ + x₂)/2, (y₁ + y₂)/2)

Connection to Pythagorean Theorem

The distance formula is essentially a² + b² = c² where:

  • a = horizontal distance (Δx = x₂ - x₁)
  • b = vertical distance (Δy = y₂ - y₁)
  • c = direct distance between points

Real-World Applications
