4. Look at the figure below.
Are triangles ABC and DEF congruent? Explain why or why not.

Answer:
Yes
Step-by-step explanation:
You see that angle D and angle A are congruent, and you see that angle C and angle F are congruent. In addition, line AC is congruent to DF. This means that yes, those triangles are congruent because of the ASA postulate.
