Unit 1, Day 6

4. Common Core GPS
MCC8.G.1: Verify experimentally the properties of rotations,
reflections, and translations:
a. Lines are taken to lines, and line segments to line segments
of the same length.
b. Angles are taken to angles of the same measure.
c. Parallel lines are taken to parallel lines.
MCC8. G. 2: 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.
