What do you mean? I don't understand how to prove it and only know what SAS stands for.

SAS means side angle side. If two sides and the angle in between them of a triangle are congruent, the triangles are congruent. if the triangles are congruent, then corresponding parts (sides and angles) of congruent triangles are congruent.

Angle ACB and Angle ECD are vertical angles. They are equal. AC = CD, which is given. BC = EC is also given. That gives you two sides that are equal and the angle in between them that is equal. Therefore, by the SAS postulate, the triangles ACB and ECD are congruent. Becuase they are congruent, corresponding sides are congruent. AB and ED are corresponding sides, therefore they are congruent (equal)
