HW: finish the handout on inequalities.

Today: Handout, double-sided, with a few properties of inequalities. Read and understand the Exterior angle inequality theorem.
Study the Triangle Inequality Theorem too. Don't mix them up.

Justin, good job today! You had all the right answers and put everything together very elegantly!

Also, Thomas great job, writing proofs even with a broken arm!
