Answer:
<h2>ΔBAC ≅ ΔDEF by AAS</h2>
Step-by-step explanation:
According to the image attached, the congruence is between triangles BAC and DEF, becayse that's the corresponding order to have an actual congruence.
Notice that angle C is congruent to angle F. Also, angle A is congruent to angle E. And side AB is congruent to side DE.
Therefore, by Angle-Angle-Side Theorem, those triangles are congruent.
