its supplementary because they add up to 180 think of it this way what is a high supplement dose 180 what has to complement each-other 90 so supplementary angles add up to 180 degrees while complementary adds up to 90 degrees

In a triangle, the sum of the measures of the angles is 180 degrees.
supplementary angles are angles that have a sum of 180*.another way to remember that its 180* is the two p's in the word make 8.example. 70*+110*= 180* supplementary.Complementary angles add up to 90 degrees.Supplementary angles are two angles whose sum add up to 180 degrees. Can be shown as (180 - x)
The sum of the internal angles is 180*(11 - 2) = 180*9 = 1620 degrees. The sum of the external angles is 360 degrees - irrespective of the number of sides.
Since the sum of all three angles is 180 degrees, the third angle is 180 - 45 - 93 =Since the sum of all three angles is 180 degrees, the third angle is 180 - 45 - 93 =Since the sum of all three angles is 180 degrees, the third angle is 180 - 45 - 93 =Since the sum of all three angles is 180 degrees, the third angle is 180 - 45 - 93 =
The angle sum of a pair of supplementary angles is 180 degrees.
