|
|
Converse of the AEA Theorem
|
If two lines are cut by a transversal forming congruent alternate exterior angles, then the lines are parallel.

|
Interior Supplements Theorem
|
If two parallel lines are cut by a transversal, then the interior angles on the same side of the transversal are supplementary.
|
|
|
Converse of the Interior Supplements Theorem
|
If two lines are cut by a transversal forming interior angles on the same side of the transversal that are supplementary, then the lines are parallel.
|
|
|
SAA Congruence Theorem
|
