This statement is true.
A triangle with angles measuring 90 degrees, 46 degrees, and 44 degrees is indeed a right triangle because one of its angles is exactly 90 degrees.
Furthermore, since all three angles are different in measure, the triangle is also classified as scalene (a scalene triangle has all sides of different lengths, which corresponds to the different angles).
Therefore, the triangle in question is correctly classified as a right scalene triangle.
