Complementary? Supplementary? Part Deux

For some updates, look below the angle pictures for some further hints. In the original post, I suggested that...


My students often can't remember which angles are complementary and which ones are supplementary. I always tell them to think of a really cheap wedding, where the complementary (free) drinks are limited to 90. Complementary angles add up to 90 degrees. "C" for "cheap" and "c" for complementary. A "superb" wedding (supplementary) would offer 180 free drinks. Supplementary angles add up to 180 degrees. "S" for "superb" and "s" for supplementary. Failing that, I tell them that "c" comes before "s" in the alphabet and 90 comes before 180.

Further Ideas!

 

1. Complementary makes a Corner

Supplementary makes a Straight Line

 

2. Bodybuilders who take vitamin supplements get bigger muscles. 180 is bigger than 90, so supplementary is 180.
