Problem : Which side of the triangle below is the longest?

Problem : In triangle ABC, if side AB = 3, side BC = 4, and side CA = 5, which angle, A, B, or C, is the smallest?

Problem : Is it possible for an exterior angle of a triangle to be smaller that one of the interior angles of the triangle?

Problem : If an exterior angle of a triangle is 95 degrees, and one of the remote interior angles is 50 degrees, what is the measure of the other remote interior angle?
