Answer:
- rotation and dilation
- translation and dilation
Step-by-step explanation:
Rotation, translation, and reflection are all rigid transformations that will result in congruent figures. Dilation (by a factor other than 1) will result in a figure of the same shape, but not of the same size, so the image is similar, but not congruent, to the original.
The applicable choices are those that include dilation.
