State
The distance formula measures between two points by the Pythagorean theorem: d = √((x₂ − x₁)² + (y₂ − y₁)²).
Show
From (1, 2) to (4, 6): the legs are 3 and 4, so d = √(9 + 16) = √25 = 5.
Watch for
The radical covers the whole sum.
Builds on
- Nothing — this is a starting point.
Unlocks
- Nothing yet depends on this.
