Explanation:

Congruent shapes have the same size and shape. Dilations are transformations that change the size of a shape (either make it larger or smaller), while congruent shapes must be identical in size. So dilations cannot be used to prove congruence.

Answer:

1. c. Identical sizes and shapes
2. d. They change the size of the shape
