Lines are taken to lines, and line segments to line segments of the same length.

24 questions2 skills

Angles are taken to angles of the same measure.

24 questions2 skills

Parallel lines are taken to parallel lines.

52 questions4 skills

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.

168 questions12 skills

Describe the effect of dilations, translations, rotations, and reflections on two-dimensional figures using coordinates.

68 questions4 skills

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

173 questions7 skills

Use informal arguments to establish facts about the angle sum and exterior angle of triangles, about the angles created when parallel lines are cut by a transversal, and the angle-angle criterion for similarity of triangles.
