What students learn

In this lesson, students understand congruence and similarity using physical models, transparencies, or geometry software.

  • Verify experimentally the properties of rotations, reflections, and translations.

  • Understand that a two-dimensional figure is congruent to another if the second can be obtained from the first by a sequence of rotations, reflections, and translations; given two congruent figures, describe a sequence that exhibits the congruence between them.
