isometry  (-sm-tr)

1. Equality of measure.

2. Equality of elevation above sea level.

3. A function between two metric spaces (such as two coordinate systems) which preserves distances. A rotation or translation in a plane is an isometry, since the distances between two points on the plane remain the same after the rotation or translation.
