Which series of transformations would map quadrilateral ABCD onto the other quadrilateral? (select all that apply) A. Reflection over the x-axis, translation right 4 B. Rotated 180 degrees, translation right 2 C. Reflect over the x-axis, reflect over the y-axis D. Rotate 90 degrees clockwise, translation left 1 and down 5

I would say D, because B wouldn't make sense too me, it's saying it's rotating, but not saying which direction, and if I were to rotate it 90 degrees clockwise, then translate it left 1, down 5, it would make more sense.

makes sense but its a select all apply question

Gucchi:

u think its only 1

ah, I didn't realize that, apologies.

Process of elimination is your friend. Let's start with A. If you were to reflect ABCD over the x-axis, where would the points be?

Gucchi:

i mean i already did all the work, i just wanted someone to confirm if i was right with D or not

I would agree, sorry for not answering earlier I was busy with some things.

Gucchi:

okay THANK YOU SO MUCH!, do you think that its just D, or another answer aswell cz its multiple choice

Gucchi:

like select all that apply*

Gucchi:

@timmyspu you here?

@sharkattack123 was i right here?

Sharkattack123:

Sorry- I'm not sure x.x

Gucchi:

oh alr then, nobody helping on this site and im so lost

Gucchi:

idk what to do man

Sharkattack123:

use gauthmath

does that help?

Sometimes

563blackghost:

Follow based on rotation formulas/ reflection formulas. Start with A. First you will pick a point, let's do point A. How would Point A change by x-axis reflection?

yeah ty for the help, but i worked it out and its A

There is another answer it is not just A.

wait really?

Gucchi:

BROO NOW I GOTTA GO BACK

563blackghost:

Have tried working out the other answers? Start with B. `180 degree rotation` is `(x,y) -> (-x,-y)` How would Point A rotate?

JaceBrooks223:

its A

it would not be B

How so? Can you work it out?

Rotating ABCD and translating would not end up at the other coordinates

Gucchi:

hello?

Sorry, im at work so im multi tasking. Point A is `(-1,1)` `(-(-1), -1) -> (1,-1)` Translate by 2 to the right, what point does it land on?

Gucchi:

(3, -1) right?

563blackghost:

yea, so that checks out. How about the other points?

Gucchi:

@563blackghost wrote:

yeah, actually the other points do match

563blackghost:

Not exactly. See the first point works out but if did point B for example. `(-3,2) rotate 180 -> (3,-2)` translate 2 right `(3+2,-2) -> (5,-2)` does that match for point F?

oh true it doesnt its way off

Gucchi:

sorry i looked at sum else

Gucchi:

Okay so B is not a choice, C is definitely not a choice since it doesnt quite reflect over the y axis

Gucchi:

The only one remaining is D

Gucchi:

..

Gucchi:

@563blackghost

Arieonna:

i think it is D

Gucchi:

dude is it A and D?

Arieonna:

if it is a abcd question there can only be 1 answer

Arieonna:

i think

Gucchi:

BRO IM CONFUSED I WANNA END THIS QUESTION

Gucchi:

its literally been 2 days

Arieonna:

is this for english

Gucchi:

?

Gucchi:

its geometry obviously

Arieonna:

oh cause if it is i am not so good at english

Gucchi:

so why u think its D

Arieonna:

i don't know i have a feeling i guest but i don't want you to be wrong if it is not D.

Gucchi:

but why D i dont get it

Arieonna:

it might relate to 90 degrees clock wise

Arieonna:

i am not to good at geomentry

Arieonna:

so that why i am afraid it might be wrong
