The correct comparison regarding dilation transformations and how they relate to translations, rotations, and reflections is:
C. Dilation transformations are the only ones that do not maintain the same side lengths.
Here's a brief explanation of each option:
- A is incorrect because translations, rotations, and reflections preserve the size and shape of figures, while dilations change the size.
- B is incorrect because dilation changes the size of figures, while translations, rotations, and reflections move them without changing their size.
- D is also incorrect because translations do not change the size of figures at all; instead, they slide them across the plane.
Thus, C is the only accurate statement regarding how dilations differ from other transformations.
