Aim: How do we use the other definitions of transformations?

Other definitions of transformations would be things such as; Glide reflections, orientation, isometry and invarient.

Glide Reflection- the combination of a reflection in a line and a translation along that line.

Orientation- orientation refers to the arrangement of points, relative to one another, after a transformation has occured.

Isometry- an isometry is a transformation of the plane that preserves length.

Invarient- a figure or property that remains unchanged under a transformation of the plane is reffered to as invarient. No variations have occured.

All of these terms are other kinds of defintions of transformation.

One of the more important and more used terms here would be isometry. Every kind of transfromation falls under the definition of isometry except for dilation.
