百科释义
In mathematics, an isometry is a distance-preserving map between metric spaces. Given a metric space, or a set and scheme for assigning distances between elements of the set, an isometry is a transformation which maps elements to another metric space such that the the distance between the elements in the new metric space is equal to the distance between the elements in the original metric space.
