Given angles of 80° and 100°, determine if they are complementary or supplementary

Two angles are complementary if their sum is equal to 90° and are supplementary if their sum is equal to 180°

Angle 1 + Angle 2 = 80° + 100°

Angle 1 + Angle 2 = 180°

Since the sum of the two angles ≠ 90°, the two angles are

Since the sum of the two angles equals 180°, the two angles
