Do you know enough to determine that AABC ~ AEDF? How do you know?
O Yes, because we can find the missing angles from each triangle to see that we have two sets of congruent angles
O No, because one set of angles are not congruent
O Yes, because ZA and ZE are congruent
O No, because you need to know that the corresponding sides are all proportional
