Question

which sequence of transformations can only be used to prove similarity between two images but not congruency? a rotated, then translated b translated, then reflected c rotated, then dilated d reflected, then rotated

Explanation:

Rotations, translations, and reflections are rigid transformations that preserve side lengths and angles, so they maintain congruence. Dilation changes the size of a figure (while keeping shape/angles), which only preserves similarity, not congruence. The sequence in option C includes dilation, so it can only prove similarity, not congruency.

Answer:

C. rotated, then dilated
