Verify experimentally the properties of rotations, reflections, and translations:
8.G.1.a Lines are taken to lines, and line segments to line segments of the same length.
8.G.1.b Angles are taken to angles of the same measure.
8.G.1.c Parallel lines are taken to parallel lines.
- 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.
Describe the effect of dilations, translations, rotations, and reflections on two-dimensional figures using coordinates.
Note: Dilations are not included in this unit or the map section shown below.
- This map shows standards 8.G.1, 8.G.2, and 8.G.3 combined.
