Which type of triangle is characterized by having no equal sides?

A triangle that has no equal sides is known as a scalene triangle. In a scalene triangle, all three sides are of different lengths, and consequently, all three angles are also different. This is a defining feature of scalene triangles, distinguishing them from the other types.

In contrast, an equilateral triangle has all three sides equal in length, making it symmetrical and regular in shape. An isosceles triangle has at least two sides that are equal, resulting in two angles being equal as well. A right triangle, while it can be scalene or isosceles, is specifically characterized by having one angle that measures 90 degrees, but it is not defined by the equality of its sides. Thus, the identification of a triangle with no equal sides corresponds accurately to the scalene triangle.
