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
DBC ≅ EAC
ASA postulate
DC = EC
