Look at the figure below. Which of the following statements could be a step in a proof that vertical angles are congruent? A) Angle APC ≅ Angle DPB because angles formed by the same pair of intersecting lines are congruent to each other.
B) Angle APC ≅ Angle DPB because angles supplementary to the same angle are congruent to each other.
C) Angle APC ≅ Angle DPB because angles adjacent to the same angle are congruent to each other.
D) Angle APC ≅ Angle DPB because angles complementary to the same angle are congruent to each other.
