1. Write 3-4 sentences describing how many acute and obtuse angles are created when 2, 3, or 4 parallel lines
are crossed by a single transversal that is not
perpendicular to them. Create pictures to help.
2. Identify how many unique acute angle measures there are
and how many unique obtuse angle measures there are,
explaining your reasoning.
3. Propose a generalization for when there are n parallel
lines, and confirm the generalization matches what was
found for the cases of 2, 3, or 4 parallel lines. Prove the
generalization, explaining all of your reasoning.
