The Euclidean mapping or isometry is a special case of affine mapping that, besides collinearity and ratios of distances, keeps also distances and angles. Because of this, a Euclidean mapping is also called a rigid motion.

Euclidean mappings are of three types:

  • translations
  • rotations
  • reflections.

A special case of Euclidean mapping is a symmetry operation.
