In the ABC triangle: AB = 18 cm, BC = 17 cm, AC = 24 cm. What is the greatest angle? A) Angle B B) Angle C C) Angle A (Prove)
Theorem: In a triangle, opposite the larger side, there is a larger angle, and vice versa, opposite the smaller side, there is a smaller angle. Since the side AC = 24 cm is the largest, it means that the angle B is the largest (since it lies opposite this side). Answer: A.
