The congruence theorem that can be used to prove that both triangles are congruent is: C. SSS.
What is the SSS Congruence Theorem?
The SSS congruence theorem is a triangle theorem which states that two triangle are congruent if they have three pairs of corresponding sides that are congruent.
The triangles in the image given have the following three corresponding sides that are congruent:
- AD ≅ CB
- DC ≅ BA
- AC ≅ CA (reflexive property)
Therefore, the congruence theorem to prove they are congruent is: C. SSS.
