Which type of triangle has no equal sides or angles?

A triangle with no equal sides or angles is referred to as a scalene triangle. In scalene triangles, each side is of a different length, and each angle is of a different measure, meaning there are no congruent sides or angles present. This characteristic distinctly separates scalene triangles from isosceles triangles, which have at least two equal sides, and equilateral triangles, where all three sides and angles are equal. Right triangles are characterized by having one angle measuring 90 degrees, but they can also be scalene if all three sides are of different lengths. Therefore, the uniqueness of the scalene triangle lies in its complete lack of symmetry, setting it apart from the other types.
