When the lines cut by a transversal are parallel lines, the measures of the angles in each pair have specific relationships.

Here is the first (considered a postulate):

(In the diagram at left, the corresponding angles are the ones marked with the same color.)

Using the Corresponding Angles Postulate (from the previous slide), it is possible to prove the following other relationships (considered theorems):

Note: Same-side (consecutive) exterior angles are also supplementary, but this is not always given a name as a theorem. Nonetheless, you may use it to solve problems.

**(Copy these theorems into your notes. Make sure you include their names! You will use all of them to answer the following questions.)**
