If two parallel lines are cut by a third plane | Then the lines of intersection are parallel |
If two parallel lines are cut by a transversal and alternate interior angles are formed | Then they are congruent |
If two parallel lines are cut by a transversal and same side interior angles are formed | Then they are supplementary |
If a transversal is perpendicular to one of two parallel lines | Then it is perpendicular to the other one also |
If two lines are cut by a transversal and alternate interior angles are congruent or if same side interior angles are supplementary | Then the lines are parallel |

Through a point outside a line | There is exactly one line parallel to and perpendicular to the given line |
If two lines are parallel to a third line | Then the lines are parallel to each other |
