Parallel Lines
Subject:
Algebra [1]
Postulates Corresponding Angles Postulate: If two coplanar lines are cut by a transversal so that two corresponding angles have the same measure, then those lines are parallel. Parallel Lines Postulate: If two lines are parallel and are cut by a transversal, corresponding angles have the same measure. Theorums Alternate Exterior Angles Theorum: If two parallel lines are cut by a transversal, the alternate exterior angles are congruent. See proof. Alternate Interior Angles Theorum: If two parallel lines are cut by a transversal, the alternate interior angles are congruent. See proof. Interior Angle Theorum: If two parallel lines are cut by a transversal, interior angles on the same side of the transveral are supplementary. See proof.
