Use two lines of notebook paper as parallel lines and draw any
transversal. Use a protractor to measure
Measure one pair of same side interior angles. Repeat the experiment with another transversal. What appears to be true?
Alan tried to prove Postulate 10 as shown below. However, he did not have valid proof. Explain why not.
If two parallel lines are cut by a transversal, then corresponding angles are congruent.
Given ; transversal cuts and

4. | Transitive Property |
What do the arrowheads in the diagram tell you?
Classify each pair of angles as alternate interior angles, same-side interior angles, corresponding angles, or none of these.
