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).
