Copy of Triangle Exterior Angle Sum Theorem

In your notes for lesson 3.2, answer the following:
1. Rotate the original triangle 180 degrees. Then translate the original triangle so that point B corresponds to point C. Make a conjecture about the relationship of an exterior angle of a triangle and its two remote interior angles.[br]2. Move points A, B, and C to change the triangle. Is your conjecture always true?
