Euclidean Distance Formula

The distance between two points (x₁, y₁) and (x₂, y₂) in a Cartesian plane is derived from the Pythagorean theorem.

d = √[(x₂ - x₁)² + (y₂ - y₁)²]

Example 1

Points: (0, 0) and (3, 4)

  • Δx = 3 - 0 = 3
  • Δy = 4 - 0 = 4
  • d = √(3² + 4²) = √(9 + 16) = √25 = 5

Example 2

Points: (-1, -1) and (2, 3)

  • Δx = 2 - (-1) = 3
  • Δy = 3 - (-1) = 4
  • d = √(3² + 4²) = 5

How to Use

  • Enter coordinates of first point (x₁, y₁).
  • Enter coordinates of second point (x₂, y₂).
