In triangle ABC, the lengths of the sides are known: AB = 19 dm, BC = 10 dm, AC = 11 dm. Which angle is the largest and which is the smallest.
By the property of a triangle, a larger side lies opposite its larger angle, and a smaller side lies against a smaller angle.
Since the AB = 19 dm side is the largest, the ACB angle will be the largest.
Since the side of СD = 10 dm is the smallest, the angle BAC will be the smallest.
Answer: The ACB angle is the largest, the BAC angle is the smallest.
