Answer:
SAS theorem
Step-by-step explanation:
If  and m∠ECD = m∠BCA, then the triangles are similar by the SAS theorem.
 and m∠ECD = m∠BCA, then the triangles are similar by the SAS theorem.
 
           
So,   and m∠ECD = m∠BCA because vertical angles are congruent
  and m∠ECD = m∠BCA because vertical angles are congruent
Therefore ΔECD is similar to ΔBCA by SAS theorem
