Review of Transformations
- Isometry Status

Topic Index | Geometry Index | Regents Exam Prep Center


Isometry - length is preserved - the figures are congruent.
Direct Isometry - orientation is preserved - the order of the lettering in the figure
     and the image are the same, either both clockwise or both counterclockwise.
Opposite Isometry - orientation is not preserved - the order of the lettering is reversed,
     either clockwise becomes counterclockwise or counterclockwise becomes clockwise.
