For the lengths of its sides

As a scalene triangle (from the Greek σκαληνός "unequal"), if all its sides have different lengths (in a scalene triangle there are no two angles having the same measure)

For its angles

obtuse triangle: if one of its interior angles is obtuse (greater than 90 °); the other two are acute (less than 90 °).
