Parallel and Perpendicular Lines

Which of the following statements is not ture

• ∠3 ≅ ∠2 because they are alternate interior angles.

• m∠1 + m∠3 = 180° because they form a straight angle.

• ∠3 ≅ ∠6 because they are alternate interior angles.

• ∠1 and ∠6 are supplementary because ∠3 ≅ ∠6 and m∠1 + m∠3 = 180°.
