Distance Between Points ಅನ್ನು ಹೇಗೆ ಲೆಕ್ಕ ಹಾಕುವುದು
Distance Between Points ಎಂದರೇನು?
The distance formula calculates the straight-line distance between two points in 2D or 3D space. It is derived from the Pythagorean theorem.
ಸೂತ್ರ
d = √[(x₂−x₁)² + (y₂−y₁)²] (2D); d = √[(x₂−x₁)² + (y₂−y₁)² + (z₂−z₁)²] (3D)
- P₁
- first point (x₁, y₁)
- P₂
- second point (x₂, y₂)
- d
- distance between points (length)
ಹಂತ-ಹಂತದ ಮಾರ್ಗದರ್ಶಿ
- 12D: d = √((x₂−x₁)² + (y₂−y₁)²)
- 23D: d = √((x₂−x₁)² + (y₂−y₁)² + (z₂−z₁)²)
- 3Midpoint: ((x₁+x₂)/2, (y₁+y₂)/2)
- 4Manhattan distance: |x₂−x₁| + |y₂−y₁|

Frequently Asked Questions
Is the distance formula symmetric?
Yes! d(P₁, P₂) = d(P₂, P₁). The order doesn't matter.
Can distance be negative?
No, distance is always non-negative. It's the magnitude of the displacement vector.
How do I find the distance from a point to a line?
Use the point-to-line distance formula: d = |ax₀ + by₀ + c| / √(a² + b²).
