Answer:
Similar but not congruent
Step-by-step explanation:
Two triangles are congruent if the corresponding sides have the same length. When we make the dilation, the length of the corresponding sides is proportional but not equal. So, they are not congruent
On the other side, two triangles are similar is the corresponding sides have proportional length. So, they are similar
Therefore, the answer is similar but not congruent.
