Understand congruence and similarity using physical models, transparencies, or geometry software.
G.16. Verify experimentally the properties of rotations, reflections, and translations: [8-G1]
G.16.a. Lines are taken to lines, and line segments are taken to line segments of the same length. [8-G1a]
G.16.b. Angles are taken to angles of the same measure. [8-G1b]
G.16.c. Parallel lines are taken to parallel lines. [8-G1c]
G.17. 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. [8-G2]
