No, an equiangular triangle cannot be scalene.
An equiangular triangle is defined as a triangle where all three angles are equal. In fact, in an equiangular triangle, each angle measures exactly 60 degrees. Since all three angles are equal, this also means that all three sides must be equal in length to maintain the equality of the angles. Therefore, an equiangular triangle is also classified as an equilateral triangle.
A scalene triangle, on the other hand, is defined as a triangle where all three sides and all three angles are different. Since an equiangular triangle has equal angles and, consequently, equal sides, it cannot meet the definition of a scalene triangle.
