3.2 : Angles Formed by Parallel Lines and Transversals
Theorems and Postulates:
Alternate Interior Angles Theorem - If 2 parallel lines are cut by a transversal, then the pairs of alternate interior angles are congruent
Theorems and Postulates:
Alternate Interior Angles Theorem - If 2 parallel lines are cut by a transversal, then the pairs of alternate interior angles are congruent
Corresponding Angles Postulate - If 2 parallel lines are cut by a transversal, then the pairs of corresponding angles are congruent
Alternate Exterior Angles Theorem - If 2 parallel lines are cut by a transversal, then the pairs of alternate exterior angles are congruent
Same-Side Interior Angles Theorems - If two parallel lines are cut by a transversal, then the two pairs of same-side interior angles are supplementary
