Is the following definition of complementary reversible? If so, write it as a true biconditional. Supplementary angles are two angles whose measures add up to 180.
a. Yes, if the angles are supplementary, their measures add up to 180.
b. Yes, angles are supplementary if (and only if) their measures add up to 180.
vs. Yes, angles are supplementary if their measures add up to 180.
D. The declaration is not reversible. the only biconditional in the list is C.
In this case, it is also the right choice. >phew< You all have to understand that we don't all have the same order in the test, someone's number one can be your number three or something like that. I don't think you two have the same quizzes as all of us. No simp is right Does it work? which honors geometry by the way
NOT REGULAR
Unit Test of Reasoning and Proof Part 1 The answer is definitely c Unit Test of Reasoning and Proof
Geometry A (junior year)
1 counterexample
2 if the next month is January, then this month is the last of the year.
assumption: next month is January
conclusion: this month is the last of the year
3 Yes, angles are supplementary if (and only if) their measures add up to 180
4 A ray is a bisector of one if and only if it divides the angle into two angles
5 Symmetric property
6 if x < 30, then x < 20; fake
counterexample: x = 27 and x < 30
7 RT-ST
8 Subtraction property of equality
9 12
10 Transitive property

17. 1=37 because 1 and 3 are congruent angles. They measure exactly the same.
18.A) Replacement
B) definition of additional angles
D) equality subtraction property
19.Additional; ∠2 and ∠3; substitution; 2.
20.
a. segment addition postulate
b. substitution
vs. simplify
D. subtraction property of equality (by 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
ADB = 2x+22
=2(11)+22
= 22+22
AMD= 44
