What is the corresponding angle postulate?
|
If two parallel lines are cut by a transversal, then the pairs of corresponding angles are congruent.
Ex: The two angles that are on the same part of the parallel lines are congruent. |
|
|
Alternate Interior Angles
|
If two parallel lines are cut by a transversal, then the pairs of alternate interior angles are congruent.
|
|
|
Consecutive Interior Angles
|
If two parallel lnes are cut by a transversal, then the pairs of consecutive interior angles are supplementary.
|
|
|
Alternate Exterior Angles
|
If two parallel lines are cut by a transversal, then the pairs of alternate exterior angles are congruent.
|
|
|
Perpendicular Transversal
|
If a transversal is perpendicular to one of two parallel ines, then it is perpendicular to the other.
|
|
|
Corresponding Angles Converse
|
If two lines are cut by a transversal so that corresponding angles are congruent, then the lines are parallel.
|
|
|
Alternate Interoir Angles Converse
|
If two lines are cut by a transversal so that alternate interior angles are congruent, then the lines are parallel.
|
|
|
