The congruence criterion that can be used to show that AABC = AADE is the SSS rule (side-side-side)
From the given diagram, we can see that triangle ABC is equal to triangle ADE since the length of CA is equal to AE.
Using the similarity theorem of the triangle:
We can see that the measurement used are the sides of the triangles, hence we can conclude that the congruence criterion that can be used to show that AABC = AADE is the SSS rule (side-side-side)
