There are many types of transformations in Geometry. Some of them are Glide Reflections, Orientation, and Isometry, Direct Isometry and Invariant.
- Glide Reflection is the combination of a reflection in a line and a translation along that line
- Orientation is the arrangement of points relative to one another after a transformation has occurred.
- Isometry is a type of transformation of the plane that preserves length. For Example: a transformation that preserves everything except dilation.
- Direct Isometry preserves orientation or order - the letters on the diagram go in the same clockwise or counterclockwise direction on the figure.
- Invariant is a figure that remains unchanged under a transformation of the plane. No variations have occurred.
