Answer:
rotation and dilation
translation and dilation
Explanation:
translation is a movement up and down or side to side
rotation is a spin
reflection makes a mirror image
dilation makes it bigger or smaller
Congruent means the same size, so we are looking for things that are not the same size. Dilation is the transformation that changes size
translation and rotation -same size so congruent
rotation and dilation changes size - similar
reflection and translation - same size -congruent
reflection and rotation - same size - congruent
translation and dilation - changes size - similar
