(A) Describe and perform transformations of figures in a plane using coordinate notation

(Y8) Define congruence of plane shapes using transformations (ACMMG200)

HSG.CO.2 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).
