Which postulate or theorem proves △ABC≅△EDC ? SAS Congruence Postulate ASA Congruence Postulate SSS Congruence Postulate HL Congruence Theorem .

Answer: SAS Congruence Postulate
Step-by-step explanation:
In ΔABC and ΔDCE
AC=CE [given]→Side
∠ACB=∠DCE [vertically opposite angles]→Angle
BC=DC [given]→Side
∴ ΔABC ≅ ΔDCE [SAS congruence postulate]
