In triangle ABC, angle A is 50 degrees, angle B is 70 degrees, and angle C is 89 degrees.

In triangle ABC, angle A is 50 degrees, angle B is 70 degrees, and angle C is 89 degrees. Which side of the triangle is the largest and which is the smallest?

Given:
triangle ABC,
angle A = 50 degrees,
angle B = 70 degrees,
angle С = 89 degrees
Find: the largest and the smallest of the sides of the triangle -?
Solution:
Opposite the larger angle lies the larger side, opposite the smaller angle lies the smallest side. Consequently, opposite the smallest angle A = 50 degrees lies the side of the smaller side BC. Opposite the largest angle C = 89 degrees lies the largest side AB.
Answer: the smallest side of triangle BC; the largest side of the triangle AB.
