Question 494516
Since the question has not been answered after two days, I'll offer mine.
The problem will come when your angle is over 90 degrees looking for a complement or over 180 degrees when looking for a supplement.
After looking up, I found conflicting answers; some said the complements have to be positive, some say negatives are used.
So, the question is controversial when considering negative complements or supplements.
Best I could find, best I can offer.
