but yes, you are in fact correct.

Actually, the answer is false. A scalene triangle is a triangle in which all three sides have different lengths. The term "scalene" refers to the sides, not the angles. The angles of a triangle can be acute (all three angles less than 90 degrees), right-angled (one angle equals 90 degrees), or obtuse (one angle greater than 90 degrees). Therefore, a scalene triangle can be acute or obtuse, but it cannot be right-angled.
