...are complementary.
SUPPLEMENTARY ANGLES are two angles the sum of whose measures is 180 degrees.
The other two angles are also 40 degrees and 140 degrees.
Two angles are considered complementary if their measures add up to 90 degrees. This means that if the sum of two angles equals 90 degrees, they are classified as complementary. Conversely, if two angles are complementary, their measures must sum to 90 degrees. Thus, the statements effectively define the same relationship between complementary angles.
Supplementary angles add up to 180 degrees
