A Scalene triangle is one in which at least two sides are equal.
Scalene triangles are triangles where each side is a different length. They are unusual in that they are defined by what they are not. Most triangles drawn at random would be scalene. The interior angles of a scalene triangle are always all different. The converse of this is also true - If all three angles are different, then the triangle is scalene, and all the sides are different lengths
