Converse of Parallel Lines

Front

What is the Converse of Corresponding Angles?

Back

If two lines are cut by a transversal and the corresponding angles are congruent, then the lines are parallel.

Front

What is the Converse of Alternate Interior Angles?

Back

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

Front

What is the Converse of Alternate Exterior Angles?

Back

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