Look at the figure shown below:

OpenStudy (anonymous):

A student made the table below to show the steps to prove that DC is equal to EC: Statements Justifications AC = BC Given m∠EAC = m∠DBC Given m∠ACD = m∠BCE Given m∠ACE = m∠ACD + m∠DCE Angle Addition Postulate m∠BCD = m∠BCE + m∠DCE Angle Addition Postulate m∠BCD = m∠ACD + m∠DCE Substitution triangleDBC ≅ triangleEAC ASA postulate DC = EC CPCTC Provide the missing statement and justification in the proof. Using complete sentences, explain why the proof would not work without the missing step.

OpenStudy (anonymous):

the missing statement is between the substitution and the ASA postulate
