If ∠3 is 75º    and ∠6 is 75º, what can you say is true about lines m and n and why?

• Lines p and q are parallel because they never intersect because they look parallel

• Lines p and q are parallel because ∠3 and ∠6 are alternate interior angles

• Lines p and q are parallel because ∠4 and ∠6 are corresponding angles

• Lines p and q cannot be parallel because ∠3 and ∠6 do not add to 180º
