translations, or slides; and reflections, or flips, are geometric
transformations that change an object's position or orientation
but not its shape or size. The interactive figures in this four-part
example allow a user to manipulate a shape and observe its behavior
under a particular transformation or composition of transformations.
like these allow students to deepen their understanding of congruence,
similarity, and reflection, and they also contribute to the study
of transformations, as described in the Geometry Standard.
