Understanding the Distance Formula: Deriving AB = √2 Using the Coordinate Plane In mathematics, especially in geometry and coordinate systems, calculating distances between points is a fundamental skill. One elegant example involves finding the distance between two points, A and B, using the 2D coordinate plane. This article explores how the distance formula works, with a clear step-by-step derivation of the distance formula AB = √[(1−0)² + (0−1)² + (0−0)²] = √2. --- ### What is the Distance Between Two Points?
