Objective: I will use the Triangle Inequality Theorem to predict the length of a third side given two side measures of a triangle. I will order sides and angles in a triangle using the relationship between the opposite sides and angles. (G.2A)
Reflect: Why must the sum of two sides of a triangle always be larger than the third side?
