Standard Identifier: 8.G.1.a

Grade: 8
Domain: Geometry

Cluster:
Understand congruence and similarity using physical models, transparencies, or geometry software.

Standard Identifier: 8.G.1.b

Grade: 8
Domain: Geometry

Cluster:
Understand congruence and similarity using physical models, transparencies, or geometry software.

Standard:
Verify experimentally the properties of rotations, reflections, and translations: Angles are taken to angles of the same measure.

Standard Identifier: 8.G.1.c

Grade: 8
Domain: Geometry

Cluster:
Understand congruence and similarity using physical models, transparencies, or geometry software.

Standard:
Verify experimentally the properties of rotations, reflections, and translations: Parallel lines are taken to parallel lines.

Standard Identifier: 8.G.2

Grade: 8
Domain: Geometry

Cluster:
Understand congruence and similarity using physical models, transparencies, or geometry software.

Standard:
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.
