Section Two
Corresponding Angles Postulate- If two parallel lines are cut by a transversal, then the pairs of corresponding angles are congruent.
Alternate Interior Angles Theorem- If two parallel lines are cut by a transversal, then the pairs of alternate interior angles are congruent.
Alternate Exterior Angles Theorem- If two parallel lines are cut by a transversal, then the two pairs of alternate exterior angles are congruent.
Same-Side Interior Angles Theorem- If two parallel lines are cut by a transversal, then the two pairs of same-side interior angles are supplementary.
