An acute scalene triangle is a type of triangle characterized by two main features: all of its interior angles are less than 90 degrees, making it acute, and all of its sides are of different lengths, classifying it as scalene.
In an acute triangle, each angle adds up to 180 degrees, and since each angle is less than 90 degrees, the triangle has a sharp, pointed appearance. The scalene aspect signifies that no sides or angles are equal, adding uniqueness to its shape. This kind of triangle has distinct properties and can be found in various geometrical applications, making it a fundamental concept in triangle geometry.
