In-Depth Guide & Mathematical Methodology
📍 Euclidean Distance & Midpoint Formula
2D Distance: Derived from the Pythagorean Theorem: d² = (Δx)² + (Δy)².
3D Distance: Generalization to 3 dimensions: d² = (Δx)² + (Δy)² + (Δz)².
Midpoint: The point exactly halfway between P₁ and P₂.
Frequently Asked Questions (FAQ)
What is the Distance Between 2 Points Calculator (2D & 3D Geometry) and how does it work?
Analytic geometry tool. Given two points in 2D $P_1(x_1, y_1)$ and $P_2(x_2, y_2)$ or 3D $P_1(x_1, y_1, z_1)$ and $P_2(x_2, y_2, z_2)$, computes straight line Euclidean distance and Midpoint coordinates.
How do I use this Distance Between 2 Points Calculator (2D & 3D Geometry)?
Select Dimension (2D Cartesian Plane vs 3D Spatial Space). Enter coordinates for Point 1 ($x_1, y_1, z_1$). Enter coordinates for Point 2 ($x_2, y_2, z_2$). View Euclidean Distance $d$ and Midpoint coordinates.
What mathematical formula is used in this calculation?
2D Distance: d = √((x2-x1)² + (y2-y1)²). 3D Distance: d = √((x2-x1)² + (y2-y1)² + (z2-z1)²). Midpoint: M = ((x1+x2)/2, (y1+y2)/2, (z1+z2)/2).
