Represent transformations in the plane using, e.g., transparencies and geometry software; describe transformations as functions that take points in the plane as inputs and give other points as outputs. Compare transformations that preserve distance and angle to those that do not (e.g., translation versus horizontal stretch).

- Rigid Motions and the Definition of Congruence
Transformations as functions on points, which ones preserve distance and angle, precise definitions of each rigid motion, and congruence defined by motion.
