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.ĭescribe the effect of dilations, translations, rotations, and reflections on two-dimensional figures using coordinates. Parallel lines are taken to parallel lines.
Lines are taken to lines, and line segments to line segments of the same length.Īngles are taken to angles of the same measure. Verify experimentally the properties of rotations, reflections, and translations: This lesson reinforces the following geometry concepts: 8.G.1
