What are two contradictions of the statement that triangle PQR is a scalene triangle?

A triangle is classified as a scalene triangle if all three of its sides have different lengths and all three of its angles are different. Therefore, if triangle PQR has at least two sides that are equal in length, it contradicts the definition of a scalene triangle. Additionally, if any two angles in triangle PQR are equal, this would also contradict its classification as a scalene triangle, since scalene triangles cannot have any equal angles.
