The diagram shows two parallel lines cut by
a transversal.

If the measure of ∠2 = (4x + 1)°, what is
the measure of ∠6? WHY?

• (4x + 1)°

  because the angles are corresponding

• (180 − 4x + 1)°

  because the angles are corresponding

• (4x + 1)°

  because the angles are vertical

• (180 − 4x + 1)°

  because the angles are vertical
