Learn how to apply hinge theorem to real life problems. The hinge theorem states that if two triangles have two congruent sides (sides of equal length), then the triangle with the larger angle between those sides will have a longer third side. By using the triangle inequality theorem and the exterior angle theorem, you should have no trouble … Chopper 1 leaves the base heading due east for 35 miles and then turns E 60º N for 22 miles.
