To prove that △DFE ~ △GFH by the SAS similarity theorem, it can be stated that StartFraction D F Over G F EndFraction = StartFraction E F Over H F EndFraction and A. ∠DFE is 4 times greater than ∠GFH.
B. ∠FHG is One-fourth the measure of ∠FED.
C. ∠DFE is congruent to ∠GFH.
D. ∠FHG is congruent to ∠EFD.
