1. In any triangles, according to the theorem on the ratio of its angles and sides, opposite the larger side is also the larger angle.
In a given triangle, the AC side has the greatest length (6 centimeters).
Therefore, ∠В is the largest.
2. The length of the BC side equal to 5 centimeters is greater than the AB side equal to 4 centimeters.
Therefore, ∠A is greater than C.
3. ∠С – the smallest of all the angles of the triangle.
Answer: ∠В – the largest of all the angles of the triangle; ∠С – the smallest of all the angles of the triangle; ∠А is more than ∠С, but less than ∠В.
