How Do We Use the Other Definitions of Transformations?

Besides the common types of transformations, there are five more types of transformations.

• Glide Reflection: the cmbination of a reflection in a line and a translation along the line.
• Orientation: refers to the arrangement of points, relative to one another after a transformation has occurred.
• Isometry: a transformation of the plane that preserves length. (an opposite isometry change the order such as clockwise changes to counterclockwise).
• Invariant: a figure or property that remains unchanged under a transformation of the plane is refered to as invarients. No variations have occurred.
• Direct Isometry (with orientation is the same): has both isometry amd same orientation (rotations).
