1A: I can identify and describe rotations, reflections, and translations (rigid transformations)
1B: I can identify and describe a sequence of transformations that maps a preimage to a congruent image.
1C: I can identify and describe a sequence of transformations that maps a preimage to a congruent image.
1D: I can identify and use the properties of rotations, reflections, and translations to justify that the figures are congruent.
