3D Geometry — Key Formulas
| Formula | Expression |
|---|---|
| Distance Formula | d = √((x₂−x₁)² + (y₂−y₁)² + (z₂−z₁)²) |
| Equation of Line | (x−x₁)/a = (y−y₁)/b = (z−z₁)/c |
| Equation of Plane | ax + by + cz + d = 0 |
| Distance Point to Plane | d = |ax₀ + by₀ + cz₀ + d|/√(a² + b² + c²) |
| Angle Between Lines | cosθ = |a₁a₂ + b₁b₂ + c₁c₂|/(√(a₁² + b₁² + c₁²) × √(a₂² + b₂² + c₂²)) |
