do you get it?

- anonymous

wait me a moment

- max1409

k

- anonymous

Well, if you'll notice - every line there gets halved except for the middle one (HK).

- anonymous

IJ is 2 units, CD is 4 units
GL is 2 units, AF is 4 units
HK is 3 units, BE is 4 units

- max1409

i still don't get it

- anonymous

No wait, HK is 2 units, AF is 3 units.

- anonymous

okay, AngusV got this

- anonymous

Damn it, I hate this notation - you get what I'm saying.

- max1409

no i don't get what your saying

- anonymous

If you want two things to be similar their proportions need to be exact.
Every single line is halved in the second figure except for the HK line which should've been 1.5 units, not 2 - because BE is 3 units long.

- max1409

k

- max1409

so what should i write for my answer?

- anonymous

his explain have it all, get it to your @.@

- anonymous

+1

- max1409

what?

- max1409

i wil medal when i find the answer

- max1409

@Leong ?

- anonymous

can say that line CD and IJ are similar because it move from 2 to 4 units
do same with AF and GL, but look at line BE and HK. BE is 3 units mean that HK have to be 1/2 of BE, which is 1.5 to be similar. Not 2 units because 4 lines above had prove. ( IJ = 1/2 CD, same with AF and GL)
Do you understand now?

- max1409

yes so will that be my answer?

- max1409

@Leong so will that be my answer?

- anonymous

You're a dense idiot, I hope you know that. We're not here to teach you how to write sentences.

- anonymous

Max, I only can give you explain, how do you answers is your own.

- anonymous

Unless you're a asian then that can be execptable

- max1409

i am close to Asian i am Russian

- anonymous

You shouldn't be taking English courses then.

- anonymous

still =.= unless you are chinese, vietnamese, japanese, korean than it acceptable

- max1409

i live in us but i struggle with geometry a lot

- anonymous

Your struggle is with writing an English sentence right now, you already have the answer.

- anonymous

Okay fine, I'll write it for you

- max1409

sorry i am really bad in geometry every other subject is easy for me

- max1409

and thx for helping me out

- anonymous

State the answers, that all you need to do =.= when they say complete answers means state it =.= not like you explain the whole universe in there =.=

- anonymous

"In my opinion, it is my utmost proficiency as a scholar of Euclidian geometry to conclude that I've witnessed a transformation in the lines of the first figure equal to one half of their original size and further projected upon the second image on all lines presented in the first figure except for one - written as BE - which did not preserve the aforementioned proportion.
Due to the measurable fact that HK line is more than half of the BE line we may therefore conclude that this disproportional projection does not reflect a similar transformation and I enclose my statement that the figures are not similar. "

- anonymous

hahahaha, I like your answer @AngusV

- max1409

lol that sounds to complicated

- anonymous

@max1409 do you even understand what he writing?

- max1409

no i don't i think he just wrote this can say that line CD and IJ are similar because it move from 2 to 4 units
do same with AF and GL, but look at line BE and HK. BE is 3 units mean that HK have to be 1/2 of BE, which is 1.5 to be similar. Not 2 units because 4 lines above had prove. just more complicated

- max1409

@Leong

- max1409

?

- max1409

@Leong what do you mean by saying this Not 2 units because 4 lines above had prove.

- anonymous

you can say that because the figure give you that

- anonymous

is not move, it 1/2 to the other

- max1409

line CD and IJ are similar because it move from 2 to 4 units and line AF and GL are similar because it move from 2 to 4 units. But line BE and HK are different BE is 3 units which means that HK has to be 1/2 of BE, which is 1.5 to be similar. does this sound good i reworded it a little?

- anonymous

=.=

- max1409

what does this mean =.=

- anonymous

Because IJ = 1/2 CD , same with AF and GL. Do you understand ?

- max1409

yes i do

- max1409

i am so confused

- anonymous

okay, now you do the same with BE and HK, because BE is 3 units and HK is 2 units so the figure is not similar since IJ = 1/2 CD and GF = 1/2 AF so HK SHOULD ALSO = 1/2 BE. Not 2. Do you understand?

- max1409

i think so but i am still a little confused

- max1409

so what should i add to this ? The image below shows two dilated figures with lines UV and WX drawn. If the larger figure was dilated using a scale factor of 4, what relationship do lines UV and WX have?

- max1409

@Leong ?

- max1409

@nincompoop

- anonymous

okay, I give up......

- max1409

please don't

- anonymous

@dejmccray here you go

- max1409

is she going to help me?

- anonymous

okay Max, this is your PROBLEM! we give you YOUR ANSWER, rewrite it into complete sentences is YOUR JOB, sr but I can't write it to you because you lazy to write it :) okay? okay.

- max1409

what do you mean i re wrote what you wrote

- max1409

?

- dejmccray

erhm I think @Leong mean reread and write what they explain and try to figure it out on your own I know your not dumb so read it slowly and carefully no one is gonna tell you the answer because you need to know this yourself sorry

- max1409

line CD and IJ are similar because it move from 2 to 4 units and line AF and GL are similar because it move from 2 to 4 units. But line BE and HK are different BE is 3 units which means that HK has to be 1/2 of BE, which is 1.5 to be similar has to be 1/2 not 2.

- max1409

is this good?

- max1409

@ Leong

- anonymous

I'm sorry, for the last time and by the power of God, do like Dejmccray say please :((

- max1409

The slope of DE is -2 and the slope of JK is -1 so that means they are not similar right because the angles are not congruent.

- max1409

is this good?

- max1409

@Leong ?

- anonymous

is not about the angle max, if you want angle, it going to be more hard to understand. Just read all the comments and think max, like i said, i'm not going to say yes or no to your answers

- max1409

and i am not lazy i just don't get it

- anonymous

okay, then just read and look at the figure, you should find it out already

- dejmccray

like I say calm down and read it slowly you will get it

- max1409

IJ is 2 units, CD is 4 units
GL is 2 units, AF is 4 units
HK is 3 units, BE is 4 units
i don't get this

- max1409

shouldn't it be like
IJ is 2 units, CD is 3 units
GL is 2 units, AF is 3 units
HK is 2 units, BE is 3 units

- max1409

@Leong ?

- anonymous

okay, IJ is 2 units, CD is 4 units
GL is 2 units, AF is 4 units
HK is 3 units, BE is 4 units ( this is right)
IJ is 2 units, CD is 3 units
GL is 2 units, AF is 3 units
HK is 2 units, BE is 3 units ( this is wrong)
why?? look at the figure and count, and see it yourself

- max1409

how can this be true if IJ is 2 units, CD is 4 units and your saying IJ is 2 units, CD is 3 units are both correct

- max1409

@Leong ?

- max1409

?

- anonymous

CD is not 3 =.= count!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! if you can look at AF, it should be the same with CD cuz is PARALLEL!

- max1409

ok so cd is 4 and ij is 3
be is 4 and hk is 3
af is 4 and gl is 3

- anonymous

hey max, one last time, THIS IS YOUR PROBLEM , WE GAVE YOU YOUR ANSWERS, PUT IT IN IS YOUR JOB! STOP PLAY DUMB OR I NEVER GOING TO HELP YOU AGAIN

- anonymous

thanks :)

- max1409

i am not playing dumb i am actually trying

- max1409

@Leong thanks for what?

- max1409

@nincompoop

- max1409

@Zale101

- max1409

anyone get it?

- Zale101

Do you think the angles are the same?

- max1409

i don't think so

- Zale101

Why not?

- max1409

i am not sure

- Zale101

Have you tried calculation the slopes or each segment in each shape?

- max1409

he slope of DE is -2 and the slope of JK is -1

- Zale101

For example. FE and LK ?

- Zale101

That means they are not the same :)
If the slopes are different, that means these two shapes are not congruent to each other.

- max1409

fe is 2 and lk 1

- max1409

the slopes

- max1409

?

- Zale101

Yes. Since you calculated DE and JK and figured the slopes were different, then the slopes will be different when you calculate the rest of the segments.
