By definition, supplementary angles are a pair of two angles forming a straight angle (180 degrees) when they are put together.
Can three or more angles be complementary or supplementary? No way!
answer: Never true

The correct answer is  "Sometimes".


It is true when the angle  A  is the right angle.

Solved.

Supplementary angles add to 180 degrees:
If
A + B = 180
and
C + B = 180
Then A = C --> But A & C *can* be equal and supplementary. That happens (only) when A = C = 90 degrees.
Sometimes true.
