Question

In an isometric transformation, the preimage and image must not __________.



A. change size
B. rotate
C.preserve angle measures

D. reflect across x-axis

Answer 1

@Dani_Rose
last one lol

Answer 2

I'm pretty sure it's A. Change size

Answer 3

Cool should I get a second opinion?

Answer 4

dani no direct answers

Answer 5

Isometric
1.
of or having equal dimensions.
2.
PHYSIOLOGY
of, relating to, or denoting muscular action in which tension is developed without contraction of the muscle.

Answer 6

ok @rebeccaxhawaii

Answer 7

I would get a second opinion if i were you

Answer 8

hey thx anyway.

Answer 12

Here's a neat acronym I found online:
"An isometric transformation means ABCD is preserved.
A is for Angle measure
B is for Betweeness
C is for Colinearity
D is for distance

When you transform an object all four of these must remain preserved.

So a dilation is not isometric as it changes the Distance of sides.
A reflection, rotation, and translation are isometric."

Answer 13

Hmm I think it's Rotation because I looked up what it means and it says Isometric transformations are transformations of the objects' position without diminishing the image or object, retaining its original shape. Furthermore, isometric transformations have three types of examples, namely, translation, reflection and rotation. Hope that helps!

Answer 14

thank both of u can only medal 1 who will it be lol

Answer 15

DUDE WAIT THAT'S WRONG XD THE ANSWER IS...

Answer 16

So, according to the acronym, you can't change angle, size (betweeness)... I'm not sure what colinearity means though, sorry

Answer 17

It's A... What I just wrote is my reason... So A.. Is the answer lol

Answer 18

Huh if that not the answer than what?

Answer 19

I'm thinking the answer is A..

Answer 20

I read that question completely wrong the first time

Answer 21

It says you can rotate, refer to the link I first posted

Answer 22

I know but read the question. "In an isometric transformation, the preimage and image must not __________."

Answer 23

@kittiwitti1 so C

Answer 24

Well, since the acronym said we must keep angle measures and size, and the link said don't rotate, we can only pick the last one... "reflect across the x-axis"

Answer 25

I think. @Directrix

Answer 26

I have no idea what this one is.. I still think it's A though.

Answer 27

and I was talking to the original poster when I said "refer to the link I first posted". Lol

Answer 28

Oh okay lol XD

Answer 29

thx gonna take a guess :o

Answer 30

Wait no, @Directrix can help you get the right answer

Answer 31

slow down xD

Answer 32

No problem! sorry I couldn't give the right answer lol ^^

Answer 33

Is he gonna help? He hasn't said anything

Answer 34

He's thinking I think @Eboogie4

Answer 35

He will. It just takes time since we're all constantly responding and he has to read through everything we've discussed

Answer 36

oh ok

Answer 37

If the pre and post images have to be congruent, then they must not change size.

Anybody agree? The ISO prefix means "the same" as in an isosceles triangle.

Answer 38

So A is Correct? lol

Answer 39

Yes I think so lol

Answer 40

Yes, it does. He is right

Answer 41

I agree with this person:

>>>I'm pretty sure it's A. Change size

In an isometric transformation, the preimage and image must not change size.

Answer 42

OH YEAH. I forgot that was NOT change size. *facepalm*

Answer 43

lol okay thanks for clearing that up for us @Directrix

Answer 44

Ok, thank you for helping @Directrix :-)

Answer 45

The question is tricky because of the "not" in it. I missed that on my first two reads.

Answer 46

So did I then I changed my answer after I read it said Not.

Answer 47

it was thank every body. I will medal @Directrix but I am a fan of all of you. A is right

Answer 48

xD alright!
Good luck on the rest~
