There are three congruence transformations. Can you name them? No, Optimus Prime is not one.

Geometry 3(A) describe and perform transformations of figures in a plane using coordinate notation;

Geometry 3(B) determine the image or pre-image of a given two-dimensional figure under a composition of rigid transformations, a composition of non-rigid transformations, and a composition of both, including dilations where the center can be any point in the plane;

Geometry 3(C) identify the sequence of transformations that will carry a given pre-image onto an image on and off the coordinate plane; and

Geometry 3(D) identify and distinguish between reflectional and rotational symmetry in a plane figure.
