C
Step by step explanation:
When you move a shape via rigid transformations, the dimensions of the shape do not change (by definition). This includes translation and rotation. Since the size or measure of any of the side lengths or angles is not changing when you move the shape, the only way that you can match one shape onto another with rigid transformations is if all of the corresponding sides and angles are congruent. Therefore, the correct answer is choice C. Hope this helps!
