Parallel lines are taken to parallel lines.

## 8.G.A.2

40 questions3 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.
