Corresponding Angles
If they occupy corresponding positions
Alternate Interior Angles
If they lie between l and m on opposite sides of t
Alternate Exterior Angles
If they lie outside l and m on opposite sides of t
Consecutive Interior Angles
If they lie between l and m on the same side of t
Postulate 15 - Corresponding Angles Postulate
If two parallel lines are cut by a transversal, then the pairs of corresponding angles are congruent
Theorem 3.6 - Alternate Interior Angles Theorem
If two parallel lines are cut by a transversal, then the pairs of alternate interior angles are congruent
Theorem 3.7 - Consecutive Interior Angles Theorem
If two parallel lines are cut by a transversal, then the pairs of consecutive interior angles are supplementary
Theorem 3.8 - Alternate Exterior Angles Theorem
If two parallel lines are cut by a transversal, then the pairs of alternate exterior angles are congruent
Theorem 3.9 - Perpendicular Transversal Theorem
If a transversal is perpendicular to one of two parallel lines, then it is perpendicular to the second
Transversal
A line that intersects two or more coplanar lines at different points
