MA.8.GR.2.1

Given a preimage and image generated by a single transformation, identify the transformation that describes the relationship.

Clarifications

Clarification 1: Within this benchmark, transformations are limited to reflections, translations or rotations of images.

Clarification 2: Instruction focuses on the preservation of congruence so that a figure maps onto a copy of itself.
