Question

Which is NOT necessarily a rhombus?

Answer 1

Is there more to your question haaha :)

Answer 2

@agent0smith @PeterPan

Answer 3

mmm having 4 right angles :)

Answer 4

^^ Yes :)

Answer 5

None of them have 4 right angles...?

Answer 6

you don't know that :P

Answer 7

Haha yeah look at the lines within the figure !

Answer 8

and anyway, that's not what matters...

obviously the first one is a rhombus, aye? :)

Answer 9

Yeah that's like your every day rhombus haha

Answer 10

what about choice B?

Answer 11

Where is choice B?

Answer 12

H?

Answer 13

Diagonals bisect each other... that's a recipe for parallelogram... aye? :>

Answer 14

oh it's H.
durr

fine, H, then.

Answer 15

I just needed that so when I look stupid I can say well look what you did.

Answer 16

aye ? :) haha thats great. Im justt going to watch now bc Peters got it . lol

Answer 17

<snaps fingers>
focus!

figure H is a parallelogram, right? :)

Answer 18

Of course

Answer 19

and... is it a rhombus, though?

Answer 20

let me ponder your first condition, @ganeshie8 as soon as I finish making my <ahem> kite.

^.^

Answer 21

I get ur point :)
first condition requires a caveat, modified conditions :

1) if diagonals are perpendicular and bisect each other, then its a rhombus
2) if all sides are equal, then its a rhombus
3) for a parallelogram, if any two adjacent sides are equal, then its a rhombus

Answer 22

yay :D

Answer 23

poor Aric xD

Answer 24

Would it be J

Answer 25

RIGHT! :I

Answer 26

maybe. why?

Answer 27

<.<

Answer 28

:)

Answer 29

Because diagonals are perpendicular and bisect each other

Answer 30

that makes for a rhombus, though...

Answer 31

and I don't see how the diagonals are perpendicular in figure J :>

Answer 32

They are there just hidden

Answer 33

oh, well, in that case what are we still doing here, all these blasted choices are rhombi, then XD

I told you not to trust these figures... they're tricksters, they are...

Answer 34

I answered G

Answer 35

because it looked unusual? :/
all it meant was that it's a parallelogram with a pair of congruent adjacent sides :/

Answer 36

I felt confident not because it is unusual

Answer 37

Sometimes the "trying to lead them to the answer" does more harm then good. People confuse me half the time. Lol maybe sometimes people should allow others to work backwards... Just my opinion though :)

Answer 38

then why G?

Answer 39

@ams98
such is geometry... not so much step-by-step as it is just 'thinking' and logic...

really tricky to do an actual 'lead them to the answer"

more often than not, it comes down do give hints on what and what isn't an answer XD

Answer 40

You are misleading I say the right answer then why and you question me and then make me second guess myself :(

Answer 41

I need to know you thought about your answer properly ^^

A correct GUESS sets a very dangerous precedent, you know :)

Answer 42

I don't consider geometry just logic. Most Geometry problems are to throw you off of the initially taught logic. What isn't the answer usually isn't always an option to explain. I believe it's better to instill traits to looks for as well as characteristics in the answer that will give you "hints" that it's correct. :)

Answer 43

but ganeshie did just that, ams... the list he gave pretty much paved the way to the answer ^^
ganeshie's list:
1) if diagonals are perpendicular and bisect each other, then its a rhombus
2) if all sides are equal, then its a rhombus
3) for a parallelogram, if any two adjacent sides are equal, then its a rhombus

(Item [1] describes H ; Item [2] describes F ; Item [3] describes G)
and since F, G, and H are definitely rhombi according to these hints, then the answer becomes clear :)

Answer 44

I agree! However Aric was unsure of the idea of the problem so when he thought he had the answer I think asking him why made him unsure of himself. Maybe Telling him the traits in which the anwser consisted of to be sure that J was infact the anwser would've taught more than having him guess at the concept... He's on here because he was unsure and reading the list when he is not sure will not fix that he does not know :) Thats all! :)

Answer 45

ams... if asking him 'why' causes him the asker to be unsure, then whether or not the answer was correct, it was probably reached far too hastily, and this is not healthy in the long run, wouldn't you say? ^.^

Answer 46

Im not even talking about this one im talking more so about the last one @PeterPan I understand why you want me to be sure of my answers but still all the answers were possible so no I was not sure and I do not have 10-20 minutes to answer a question.

Answer 47

I would say that explaining what is wrong as well as RIGHT would be more helpful... In other questions you wont always be looking just at what is wrong the same as you wont eliminate by always knowing what is only right. By giving him a list of unknown material i feel we're just dragging out the answering process. I do online schooling now and couldn't spend 20 minutes on a single question either :)

Answer 48

I understand aric ^^
But you mustn't be afraid to make mistakes here of all places, where your mistakes do not count against you, they're not recorded or anything like that...

now I'm sure you had some reason to select your answer, J, and when I asked why, it would probably have been better to state that reason, even if it *may* have been wrong, instead of maybe panicking and switching to another...

Answer 49

I would have been better off telling my teacher that none of the answers were right as

Answer 50

But I'l quit being a bother now (; haha i just know how it is to basically be fed information that is not exactly helping me if i am unsure of the information. Rant over. :) haha and i don't think it was scared just thats what why ushally implies in real life class thats all. If you have the right anwser your teachers don't question :) Aric feel free to tag me if ya have another question!~

Answer 51

Which MUST be a square?

Answer 52

Well then, the answer is indeed J, but the reason is that it doesn't explicitly state that the diagonals are perpendicular, there is no 'right angle' sign on it, so it may not be perpendicular, and the figure may not be a rhombus.

It's that simple... it's the only one that doesn't fit any of ganeshie's criteria
1) if diagonals are perpendicular and bisect each other, then its a rhombus
2) if all sides are equal, then its a rhombus
3) for a parallelogram, if any two adjacent sides are equal, then its a rhombus

Answer 53

Which MUST be a square?
I thought this one was worded the same as in my previous one

Answer 54

different choices though?

Answer 55

I thought that it was asking me which one MUST be a rhombus

Answer 56

But I still was throwing random stuff out
