Distance between two points

Pythagoras turned into a coordinate formula.

The distance between two points (x₁, y₁) and (x₂, y₂) is just Pythagoras applied to coordinates.

Drag the two points

distance = √(6² + 4²) = 7.21

Distance

d = (x_{2} - x_{1})^{2} + (y_{2} - y_{1})^{2}

Try it

Distance between (1, 2) and (4, 6)

√(9 + 16) = √25 = 5.
