Is the following definiiton of supplementary reversible? If yes, write it as a true biconditional.

Supplementary angles are two angles whose measures sum to 180.
a. Yes, if angles are supplementary, the their measures sum to 180.
b. Yes, angles are supplementary if (and only if) their measures sum to 180.
c. Yes, angles are supplementary if their measures sum to 180.
d. The statment is not reversible.

Y’all have to understand that not all of us have the same order in the test, someone’s number one can be your number three or something.

the only biconditional in the list is C.

As it happens, it is also the correct choice. >whew<

I don't think you both have the same quizzes like the rest of us do.

Non simp is right
