We continued our work with proofs and various vocab words today. Today's lesson focused on three specific types of angle pairs: complementary, supplementary, and vertical angles. The numbers 90 and 180 cropped up again, and we showed how to work with these angle pairs with both proof statements and angle calculation problems. Several of the problem types are mental math, so the homework includes several mental math problems for the students to work on.
