It is to be expected that a triangle will always have acute interior angles. If one of the interior angles is obtuse, then it is the only such interior angle, and the other two interior angles are acute.The triangle is then called obtuse. Same is true if one of the interior angles is a right angle (the other two angles are acute.) The triangle is then called a right triangle. If the greatest interior angle is an acute angle, then all the angles are acute, so it becomes logical to call the triangle an acute triangle.
