Answer:

the sum of angles must be 180 degrees

Step-by-step explanation:

The definition of supplementary angles is

"Two angles are supplementary angles if their sum is 180 degrees".

For example, if x and y are supplementary angles then

x + y = 180

Therefore, we can conclude that the requirement of supplementary angles is " the sum of angles must be 180 degrees".
