QuestionWhich postulate or theorem proves that $\triangle C F E$ and $\triangle D F E$ are congruent? SAS Congruence Postulate AAS Congruence Theorem HL Congruence Theorem SSS Congruence Postulate

Studdy Solution
Choose the appropriate postulate or theorem for proving congruence:
Since both triangles are right triangles, and we know the hypotenuse and one leg ($FE$) are equal, we use the Hypotenuse-Leg (HL) Congruence Theorem.
The postulate or theorem that proves $\triangle CFE$ and $\triangle DFE$ are congruent is:
$$\boxed{\text{HL Congruence Theorem}}$$
