Answer:
Yes, they will be.
Step-by-step explanation:
Congruent means when they are the same shape and same size.
If triangle ABC is dilated to form triangle DEF, that means that they will have the same shape and the same size.
So yes Triangles ABC and DEF will be congruent to one another because they will be the same shape, and they will have the same size as well.
