Given a triangle ABC, angle a = 120 degrees, angle b = 40 degrees, angle c = 20 degrees. Which side is the largest and which is the smallest?
By the property of the sides of an arbitrary triangle, opposite the larger side of the triangle lies the larger angle of the triangle, and against the smaller side – the smaller angle.
The angle ABC is smaller, which means the side AB is the smallest.
The BAC angle is large, which means the largest side of the BC.
Answer: The BC side is the largest, the AB side is the smallest.
