Answer:
ASA
Step-by-step explanation:
We can see that the two boxes represent 90-degree angles. This is the first "A" in ASA.
Next, we can see that the two dashes on the sides represent two congruent sides. This represents the "S" in ASA.
Lastly, since the angles by point E are vertical angles they will also be congruent, giving us the last "A" in ASA and prooving congruence.
