The 52 pages that link to Euclidean space, each with the reason it gives.
Convex setRelated: Euclidean geometry supplies familiar examples and visual tests of convexity.
IsometryRelated: Its distance-preserving maps connect the abstract definition to familiar geometry.
LaplacianRelated: The familiar sum-of-second-derivatives formula assumes a flat Euclidean setting.
Affine spaceRelated: Its underlying geometry can be treated as affine after omitting the origin.
Coordinate chartRelated: A chart maps manifold points into this familiar coordinate space.
Basis (topology)Related: Open balls in Euclidean space provide a canonical basis.
Random vectorRelated: It is a common value space for finite-dimensional random vectors.
3-manifoldRelated: Three-dimensional Euclidean space supplies the local model for every point.
3-sphereRelated: Its standard equation measures distance from the 3-sphere’s center.
