A pair of parallel lines is intersected by a transversal. Select each statement that can be used to show that ∠4 is congruent to ∠6. Options:

∠4 and ∠6 are vertical angles, so ∠4 is congruent to ∠6.

∠4 and ∠6 are alternate interior angles, so ∠4 is congruent to ∠6.

∠4 and ∠6 are alternate exterior angles, so ∠4 is congruent to ∠6.

∠4 and ∠8 are corresponding angles, and ∠6 and ∠8 are vertical angles, so ∠4 is congruent to ∠6.

∠4 and ∠8 are vertical angles, and ∠6 and ∠8 are corresponding angles, so ∠4 is congruent to ∠6.
