Went over proof assessments using peer experts. Talked about retakes and other bits of housekeeping, then learned about the triangle angle sum theorem and discovered it using a hands on activity and then proved it using Euclid's 5th postulate followed by congruent alternate interior angles. Then did a variety of 'angle chases' using the triangle angle sum theorem.
