Question

A triangle has angles measuring 10°, 40°, and 130° with side lengths of 23 cm, 84 cm, and 100 cm. Classify this triangle by its angles and sides.

Answer 1

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 °).
