All right angles are congruent | Right Angles Congruence Theorem |
If two lines are cut by a transversal and co-interior angles are supplementary, then the two lines are parallel | Co-Interior Angles Converse |
If two lines are parallel to the same line, then they are parallel to each other | Transitive for Parallel Lines |
Vertical Angles are congruent | Vertical Angles Congruence Theorem |
If two parallel lines are cut by a transversal, then the pairs of alternate interior angles are congruent | Alternate Interior Angles Congruent |
If two parallel lines are cut by a transversal, then the pairs of alternate exterior angles are congruent | Alternate Exterior Angles Congruent |
If two parallel lines are cut by a transversal, then the consecutive interior (co-interior) angles are supplementary | Consecutive Interior (Co-Interior) Angles Supplementary |
If two lines are cut by a transversal and alternate interior angles are congruent, then the two lines are parallel | Alternate Interior Angles Converse |
If two lines are cut by a transversal and alternate exterior angles are congruent, then the two lines are parallel | Alternate Exterior Angles Converse |
