In the drawing below, lines a and b are parallel lines cut by the transversal c. Jeremiah wishes to find angles that are congruent to ∠7 in order to prove that ∠7 ≅ ∠3



Which angles are congruent to ∠7? Why are they congruent to ∠7? Select two that apply.
A
∠8 because linear pairs are congruent
B
∠6 because vertical angles are congruent
C
∠4 because alternate interior angles are congruent
D
∠3 because corresponding angles are congruent
