Geometry and Spatial Sense: Congruency

Congruency: Two objects, pictures, or drawings are concruent if there exists a sequence of transformations involving translations/slides, rotations/turns, and/or reflections/flips that transforms the first shape to the second. Congruency is a fundamental concept in gometry.
