This looks like a fill-in the blanks question for a two column proof :]

3. CPCTC

The reasoning for this is that because triangle ABC and EDC are congruent, their corresponding parts are also congruent, (CPCTC; Corresponding Parts of Congruent Triangle are Congruent) or AC = EC

4. ACE

Because AC = EC, triangle ACE is isosceles

5. Base Angles Theorem

The base angles of a isosceles triangle are congruent
