3.6 Proving Lines are Parallel

Question 1

Corresponding Angles Converse Postulate

Answer 1

If two lines are cut by a transversel so that corresponding angles are congruent, then the lines are parallel

Question 2

Alternate Interior Angles Converse Theorem

Answer 2

If two lines are cut by a transversal so that alternate interior angles are congruent, then the lines are parallel

Question 3

Consecutive Interior Angles Converse Theorem

Answer 3

If two lines are cut by a transversal so that consecutive interior angles are supplementary, then the lines are parallel

Question 4

Alternate Exterior Angles Converse

Answer 4

If two lines are cut by a transversal so that alternate exterior angles are congruent, then the lines are parallel
