Which postulate or theorem proves that △cfe and △dfe are congruent?

hl congruence theorem

sss congruence postulate

aas congruence theorem

sas congruence postulate

The correct answer is:

SAS

Explanation:

In the diagram, we have that CE and ED are congruent.

We also know that ∠FEC≅∠FED; this is because these two angles form a linear pair.  A linear pair has a sum of 180°; since m∠FED = 90°, this means that m∠FEC = 180-90 = 90°, and the two angles are congruent.

We also know that FE = FE, due to the reflexive property.

This gives us two sides and the angle between them, or SAS.
