Question

Does anyone know how to do proofs for Geometry?

Answer 1

estudier :)

Answer 2

No. Nobody does.

Answer 3

Ask estudier?

Answer 4

Give me one though. I'll give it a shot.

Answer 5

In general a proof is going to go like this:
I know some basic information about the shapes. My proof begins with "Assume _____" where that blank is what you know.

Answer 6

Then you make some conclusions that follow from that assumptions, then some more and some more until you conclude what you're trying to prove.

Answer 7

Then you write "QED" 'cause you got mad style like that.

Answer 8

me?

Answer 9

Segment UV is congruent to segment XY and VW is congruent to segment WX, and segment WX is congruent to segment YZ. (Write a complete proof by rearranging the reasons listed as soon as I finish typing it out) :)

Answer 10

Hi hahd!!! xD

Answer 11

what do we have to prove?

Answer 12

Any image that needs to be attached?

Answer 13

and hi jessica

Answer 14

1.Transitive property of segment congruence
2.addition property of equality
3.definition of congruent segments
4.given
5.segment addition postulate
6.definition of congruent segments
7.substitution property of equality

Answer 15

Idk. How to attach an image.

Answer 16

it says attatch file on bottom

Answer 17

Those are going to be reasons you can claim something.

Answer 18

anyway ill let smooth math do it he sounds senior, my friend just called me over, ill be back later

Answer 19

Yes, I have to rearrange it into another proof but I feel completely lost.

Answer 20

and estudier is here u are all set

Answer 21

We still need to know the statement to be proven. And we might need an image.

Answer 22

Aw......ok then....Bye hahd! x)

Answer 23

bye

Answer 24

Are you sure "and segment WX is congruent to segment YZ."
is not THEN segment WX is congruent to segment YZ.

Answer 25

I don't actually know 2 column either. I do it up pro style or no style.

Answer 26

Oh yeah....your right. Lol, thanks that was my mistake. :)

Answer 27

You confused a lot of people. I bet they can help you now.

Answer 28

Thank you Phi!

Answer 29

Okay then.

To Prove: If segment UV is congruent to segment XY and VW is congruent to segment WX, then segment WX is congruent to segment YZ.

Answer 30

Yes. That is correct. :)

Answer 31

I think we need the image.

Answer 32

Did I do something wrong?!!??!??!?!? It's yellow!!!!!!!

Answer 33

Is it saved on your computer somewhere? If it is, click attach file, find the file and select it.

Answer 34

No.....it's in my textbook..... :,(

Answer 35

Draw it for us then.

Answer 36

Just list out the order of the points.

Answer 37

Haha didn't know you were a Twiddla hater, Estudiar.

Answer 38

O------O------O------O------O-----O
U V W X Y Z

Answer 39

What is a twiddla?

Answer 40

To Prove: If segment UV is congruent to segment XY and VW is congruent to segment WX, then segment WX is congruent to segment YZ.

Answer 41

Yes. We need the actual picture. That's not enough information to prove it.

Answer 42

.....I'll try the tweedle thingy.....

Answer 43

Answer 44

Did you leave out a sentence in the problem?

Answer 45

Can you take a picture of the page in the textbook and attach it ?

Answer 46

Idk. How would I "paste" it?

Answer 47

you would use the Attach File button below.

Answer 48

I only have my cell phone....

Answer 49

You guys can go somewhere else. :) It'll take a while to type it out.

Answer 50

Or people.....not guys...

Answer 51

1.Segment UV is congruent to segment XY, segment VW is congruent to segment WX, segment WX is congruent to segment YZ
[Reasons: Transitive property of segment congruence]
2.Segment VW is congruent to segment XZ
[Reason: Addition property of equality]
3.Segment UV is equal to XY, VW is equal to YZ
[Reason: Definition of congruent segments]
4.UV+VW=XY+YZ
[Reason: Given]
5.UV+VW=UW, XY+YZ=XZ
[Reason: Segment addition postulate]
6.UW=XZ
[Reason: Definition of congruent segments]
7.Segment UW is congruent to segment XZ
[Reason: Substitution property of equality]

Answer 52

so the goal is to rearrange the above, right ?

Answer 53

Yes :)

Answer 54

lol this is interesting..

Answer 55

aroub, if you scroll up - you will see the diagram (line with letters).

Answer 56

Start with #4 :) ?

Answer 57

Me?

Answer 58

ok!

Answer 59

letter x ?

Answer 60

...........what now? [O_____O]
-{____}-
(( ))

Answer 61

Are you sure about 2) ?

Answer 62

are we supposed to use all the steps ?
is there any other info (such as what we need to prove) ?

Answer 63

Yes, #2 is correct. Any other info? No.....not that I know of. :)

Answer 64

I can see VW congr. to YZ or
UW congr to XZ

Answer 65

?

Answer 66

???? chaise? I don't get your post....

Answer 67

2 must be a typo or bad eyes! It must be UW is congruent to XZ
note as it is written it conflicts with 7 UW is congruent to XZ

Answer 68

????????????????????????!!!!!!!!!!!!!!!!!!!!!!!??????????????????!!!!!!!!!!!!!!
WHAT!?!?!?!?!

Answer 69

Sorry...that was for those chaise persons.....

Answer 70

Jessica, can you confirm what is the correct statement for #2 ?

Answer 71

2. Segment VW is congruent to segment YZ
[Reason: Addition property of equality]

Answer 72

1.Segment UV is congruent to segment XY, segment VW is congruent to segment WX, segment WX is congruent to segment YZ
[Reasons: Transitive property of segment congruence]
2.Segment VW is congruent to segment XZ
[Reason: Addition property of equality]
3.Segment UV is equal to XY, VW is equal to YZ
[Reason: Definition of congruent segments]
4.UV+VW=XY+YZ
[Reason: Given]
5.UV+VW=UW, XY+YZ=XZ
[Reason: Segment addition postulate]
6.UW=XZ
[Reason: Definition of congruent segments]
7.Segment UW is congruent to segment XZ
[Reason: Substitution property of equality]

if u just want rearrange them..

then 1..Segment UV is congruent to segment XY, segment VW is congruent to segment WX, segment WX is congruent to segment YZ [Reasons: Transitive property of segment congruence]
2.Segment VW is congruent to segment XZ [Reason: Given]
3..Segment UV is equal to XY, VW is equal to YZ [Reason: Definition of congruent segments]
4.UV+VW=XY+YZ [Reason: Addition property of equality]
5.UV+VW=UW, XY+YZ=XZ
[Reason: Segment addition postulate]

Answer 73

i assumed that 2 is given am i right jessica? (i mean do u have it as a given?)

Answer 74

She just reposted, and it makes more sense now.

2. Segment VW is congruent to segment YZ
[Reason: Addition property of equality]

Answer 75

Lol, I think so.... In the book it is like this:
Prove-> Segment UW is congruent to segment XZ

Answer 76

ok jessica they actually write : given:.... , proof...

so whats the given u have??

Answer 77

a pic is worth a thousand words :)

Answer 78

oh and do u have any graph, picture anything..????

Answer 79

lol yea!! it makes work so much easier!!

Answer 80

O------O------O------O------O-----O
U V W X Y Z

Answer 81

Segment UV is congruent to segment XY, segment VW is congruent to segment WX, segment WX is congruent to segment YZ.


............................do I have to go on the tweedle again???

Answer 82

so that's the given - correct ? :)

Answer 83

Yes, x)
Does that help?

Answer 84

kinda - at least we know what the first and last steps need to be :)

Answer 85

yes it helps!!!!!

Answer 86

Ok! X[
(Beast mode!)

Answer 87

Segment UV is congruent to segment XY, segment VW is congruent to segment WX, segment WX is congruent to segment YZ
reason : given

Answer 88

Yes :)

Answer 89

so, Jessica , when you posted the seven steps - you had a reason associated with each og them already. Is that how it was written in the book ?

Answer 90

Yes. The reasons are to the right. And the statements on the left.

Answer 91

the way you posted it - the reason for the below was not "reason: given" :

Segment UV is congruent to segment XY, segment VW is congruent to segment WX, segment WX is congruent to segment YZ

Answer 92

.....did I mess up on something?

Answer 93

ah! can u pleaseee post a picture!!??

Answer 94

Are you supposed to draw lines connecting the statements on the left with the reasons on the right ?

Answer 95

we'll give you a medal if you post a picture !!! :)

Answer 96

yyeeeesss!!!!

Answer 97

No, the statements are to the left and the reasons are to the left of them.
GAaaaaaaaaaaaaaahhhhhhhhhhhhhh!!!!!!!!!!!!!!!!! Look on the tweedle the tweedle! There is a redonkulous picture there! Dx

Answer 98

what-eva :)
