Question

i need some answers checked

Answer 1

@Vocaloid

Answer 2

good

Answer 3

good

Answer 4

good

Answer 5

good

Answer 6

<3 and <6 are not alternate interior angles (otherwise they would be congruent)

notice how they ~substituted~ angle 6 for angle 2 into statement 2 to get statement 4

Answer 7

alright

Answer 8

good

Answer 9

they both add up to 180 not 90 so they're supplements not complements

Answer 10

uh
I'm not 100% sure but a two column proof doesn't actually use complete sentences

a paragraph proof combines the info in a two column proof and puts it into sentences so paragraph proof is a bit better matching the description

Answer 11

I really wouldn't know this one (not sure how this proof works) but they already used substitution property of equality so I guess symmetric is a better choice

Answer 12

for a transversal the two lines are parallel not perpendicular

so false

Answer 13

your answer is right but there is again one right too

Answer 14

good

Answer 15

@princeevee ok ?

Answer 16

@princeevee how you think what chice may be right again ?

Answer 17

choice

Answer 18

let's let princeeevee have a little time to think/get the next question ready

Answer 19

have to be careful with this one

2 and 8 are alternate exterior angles but that's not the logic they used to prove it

they used the fact that

2 is congruent to 6
6 is congruent to 8
therefore 2 is congruent to 8

remember what this property is?

Answer 20

B?

Answer 21

it's in the form

if A then B, if B then C, therefore if A then C

which is the transitive property

Answer 22

alright..

Answer 23

that's not quite how the addition property of equality works, just because there's a plus sign and equals doesn't mean that's the property being used

addition property of equality would be taking a statement like A = B and stating that A + C = A + B

Answer 24

since the original statement is saying that <1 and <2 are a linear pair thus adding up to 180 this is the linear pair postulate

Answer 25

** addition property of equality would be taking a statement like A = B and stating that A + C = B + C

Answer 26

oh, alright

Answer 27

not quite, statement 6 hasn't yet proven that the lines are parallel

statement 5 is saying that angle 1 and 2 have equal measures

therefore statement 6 is saying that they're congruent

this is the definition of congruent angles

Answer 28

hm, not quite

you solved for x and got 41 but it's not asking for x, it's asking for AE

so you need to calculate 4x + 5

Answer 29

if x = 41

4x + 5 = ?

Answer 30

if x = 41 you can replace "x" with "41"

therefore 4x + 5 = 4(41) + 5 = ?

Answer 31

110?

Answer 32

order of operations

4 * 41

then add 5

Answer 33

169

Answer 34

good so 169 = your sol'n

Answer 35

good

Answer 36

excellent

Answer 37

good

Answer 38

good

Answer 39

hm, not quite. "exterior" means they need to be on the outside of the two parallel lines. (so only angles 1,2,7,8) how many pairs is this?

Answer 40

4, yeah.

Answer 41

4 total angles

"how many pairs" a pair is 2

so 4/2 = 2 pairs

Answer 42

perpendicular lines ~have~ to intersect at 90 (otherwise they're not perpendicular) so false

Answer 43

this one is false because C cant be parallel to anything

Answer 44

hm. :S depends on how literally they want you to interpret the question. generally in math we don't assume something is parallel just because it looks parallel.

Answer 45

so i'ts true?

Answer 46

let's go with false for now i guess :S poorly worded question

Answer 47

@princeevee my opinion that is true

Answer 48

bc. b is parallel to a and d

Answer 49

alright, thank you, I wasn't quite sure about this one (they never actually stated that a and d were parallel which confused me)

Answer 50

ok i understand but in this case how is this that there is attached an image so from this image is clearly that b is parallel to a and d
