The 9 pages that link to Distance formula, each with the reason it gives.

• CircleRelated: Applying it to the center yields the circle equation.

• Cartesian coordinate systemRelated: Coordinate differences yield geometric distance through the Pythagorean theorem.

• Euclidean distanceBroader topic: In two dimensions, it expresses Euclidean distance using horizontal and vertical coordinate differences.

• Coordinate geometryRelated: It converts the coordinate differences between points into geometric length.

• Analytic geometryRelated: It converts coordinate differences into geometric lengths.

• Line segmentRelated: It calculates a segment’s length from the coordinates of its endpoints.

• Nth rootRelated: Euclidean distance is a square root of the sum of squared coordinate differences.

• Solid geometryRelated: It measures lengths between vertices and other points in space.

• Segment Addition PostulateRelated: On a single coordinate line, it makes the addition of adjacent distances explicit.
