Distance Formulas
2D Euclidean Distance
Example: Distance from (0,0) to (3,4) = √[(3-0)² + (4-0)²] = √[9 + 16] = √25 = 5
3D Euclidean Distance
Example: Distance from (0,0,0) to (1,2,2) = √[1² + 2² + 2²] = √9 = 3
Manhattan Distance (Taxicab)
Distance if you can only move along axes (like city blocks). Always ≥ Euclidean distance.

What's the difference between 2D and 3D distance?
2D uses x and y coordinates (flat plane). 3D adds z coordinate (depth/height). Formula adds one more squared term: √[(x₂-x₁)² + (y₂-y₁)² + (z₂-z₁)²]
Can distance be negative?
No! Distance is always positive or zero. It represents magnitude only. If you need direction, use vectors instead.
What if my coordinates are negative?
No problem! The formula works with negative numbers. When squared, they become positive anyway. Example: (-3)² = 9.
How is this related to the Pythagorean theorem?
The distance formula IS the Pythagorean theorem! For (0,0) to (3,4): horizontal = 3, vertical = 4, hypotenuse = √(3² + 4²) = 5.
When should I use Manhattan distance instead?
Use Manhattan when movement is restricted to axes (city streets, grids). Use Euclidean for straight-line, unrestricted movement (flying, straight paths).
