A 4-sided figure has 4 corners labeled E, G, D, C starting from the top-left corner and going clockwise. A line cuts through the
shape from point C to point G and contains point F. Another line cuts through the shape from E to point F. Angle C E G is a right angle. 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.
