Question
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.

the only biconditional in the list is C.
As it happens, it is also the correct choice. >whew<

17. 1=37 because 1 and 3 are congruent angles. They measure the exact same.
18. A) substitution
B) definition of supplementary angles
D) subtraction property of equality
19.Supplementary; ∠2 and ∠3; substitution; 2.
20.
a. segment addition postulate
b. substitution
c. simplify
d. subtraction property of equality(subtracting 8 from both sides) e. division property of equality(divide 8 by both sides)
21. All squares are quadrilaterals.
22.
Given - 7y=8x-14 : y=6
Substitution Property - 7(6)=8x-14
Distributive Property - 8x-14=42
Addition Property - 8x=56
Division Property - x=7
23.
ABD = ABC
2(2x+22) = 8x
4x+44 = 8x
44 = 8x-4x
44 = 4x
44/4 = x
11 = x
x = 11
ABD = 2x+22
=2(11)+22
= 22+22
ABD= 44
1-17 100% correct, idk about 18-23 though
