### Corresponding Angles Converse

if two lines are cut by a transversal so that corresponding angles are congruent, then the lines are parallel.

### Alternate Interior Angles Converse

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

### Consecutive Interior Angles Converse

if two lines are cut by a transversal so that consecutive interior angles are SUPPLEMENTARY then the lines are parallel.

### Alternate Exterior Angles Converse

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

### Parallel Transitive Theorem

if two lines are parallel to the same line, then they are parallel to each other.

### ⊥'s Parallel Theorem

in a plane, if two lines are perpendicular to the same line, then they are parallel to each other.

If m⊥p and n⊥p, then m is parallel to n

### Slope of Parallel Lines Postulate

in a coordinate plane, two nonvertical lines are parallel if and only if they have to same slope. Any two vertical lines are parallel.

### Slopes of Perpendicular Lines Postulate

in a coordinate plane, two novertical lines are perpendicular if and only if the product of their slope is -1.
Vertical and horizontal lines are perpendicular.
