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.

Answer 1

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

do me a favor and text VOTE to 954-954 since I gave you absolutely everything for this quiz please :)

Answer 9

1) counterexample
2) Next month is february, so this month is the last month of the year
Hypothesis this month is th elast of the year
conclusion next month is February
3) Yes, angles are complementary if and only if there sum measures to 90

Answer 10

The anserw is definitly c

Answer 11

Its D

Answer 12

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.

Answer 13

Non simp is right

Geometry A (Junior year)

1 counterexample
2 if next month is January, then this month is the last of the year.
hypothesis: Next month is January
conclusion: This month is the last of the year

3 Yes, angle are supplementary if (and only if) their measures sum to 180
4 A ray is a bisector of an if and only if it splits the angle into two angles
5 Symmetric Property
6 if x < 30, then x < 20 ; false
counterexample: x = 27 and x < 30
7 RT - ST
8 Subtraction Property of Equality
9 12
