Last of the Triangle Inequalities

Tuesday's notes started with a review of the Triangle Exterior Angle Inequality theorem:
From there, we discussed that the measure of an exterior angle must always be greater than the measure of either non-adjacent interior angle. The students made this conclusion because it takes both added together to make an equivalent amount to the exterior angle.
Homework: Worksheet "Triangle Sums". This worksheet is review of concepts taught earlier in this unit.
