based on the diagram, which reason justifies this statement? if ∠cef is complementary to ∠dcf, then ∠dcf ≅ ∠feg. complements of the same angle are congruent. complements of congruent angles are congruent. supplements of the same angle are congruent. supplements of congruent angles are congruent.
Answer
Answer:
Complements of the same angle are congruent.
Brief Explanations:
Since ∠CEF is complementary to ∠DCF and ∠CEF is also complementary to ∠FEG (as ∠CEG = 90°), ∠DCF and ∠FEG are complements of the same angle ∠CEF. So, by the property that complements of the same angle are congruent, ∠DCF ≅ ∠FEG.
