Which postulate or theorem proves that △abc and △edc are congruent?

the 3rd choice i think

Step-by-step explanation:

Both SAS and AAS Congruence theorem

Step-by-step explanation:

Congruent sides or angles are known to be equal in side length and angle. It does not really matter the plane on which they lay.

There are five Congruence theorem;

SSS, ASA, SAS, AAS and HL theorem.

In SSS, all the sides must be equal, While SAS, depicts equal consecutive S-A-S. HL is mainly applicable to right angle triangles only.

The triangles in the image shows two equal sides;

AC = EC and DC = BC , while the angle C are equal and between both sides.

he has now walked a total of what?

if i know what this is maybe i can
