Question

What set of reflections and rotations would carry rectangle ABCD onto itself? (4 points)



reflect over the y-axis, reflect over the x-axis, rotate 180°
rotate 180°, reflect over the x-axis, reflect over the line y=x
reflect over the x-axis, rotate 180°, reflect over the x-axis
rotate 180°, reflect over the y-axis, reflect over the line y=x

Answer 2

its c?

Answer 3

hi again :)

Answer 4

@563blackghost i think that is correct but let my friend check it lol im not good with this type of math

Answer 5

alrighty tighty

Answer 6

Answer 8

If parallelogram ABCD was reflected over the y-axis, reflected over the x-axis,and rotated 180°, where would point A' lie? (2 points)



(-4,1)
(1,-1)
(1,1)
(-4,-1)

Answer 9

i think its (-4,1)

Answer 10

Answer 11

sorry sorry i was helping someone

Answer 12

its totally cool i just spammed you with tags just because :)

Answer 13

hopefully you not offended :(

Answer 14

i told both answers are they correct?

Answer 15

Not offended at all :)

Answer 16

Well for the second one we see that the shape is reflected over the y-axis in which the points go from `(-x,y) to (x,y)` and then it is reflected across the x-axis in which the points go from `(x,y) to (-x,-y)` and then the are rotated 180 degrees in which the quadrent it will go to is the diagonally across....so the points would head right back to `(-x,y)` So you are correct :)

Answer 17

yay :)

Answer 18

For the first one I would not think it is C becuase if we reflect over the x-axis it would be in the 3rd Quarent in which we would then rotated it 180 in which it would then be in the 1st quadrent and then we would once again reflect across the x-axis in which it would land in the 4th quadrent....

Answer 19

What would be your second answer for the first one?

Answer 20

no idea

Answer 21

sorry for the wait

Answer 22

Well lets start with the first one A....`reflect over the y-axis, reflect over the x-axis, rotate 180°`

So we would reflect over the y-axis in which it would translate to the 1st quadrant....Next we would reflect to the x-axis....the quadrant below the 1st quadrant is the 4th quadrant so that is the second step.....Next it is said to rotate 180 degrees...as said before when rotation 180 degrees it will transfer to the quadrant diagonally across the one you are in....so it would land in the 3rd quadrent...does it land on itself?

Answer 23

hold on just got this

Answer 24

im confused

Answer 25

its A

Answer 26

Correct :)

Answer 27

yeah um i guessed :P

Answer 28

im so lost idek

Answer 29

yeah i wont understand it so dont bother trying to explain it

Answer 30

unless you want too

Answer 31

did you freeze

Answer 32

The shape is currently in the 2nd quadrent....we are given a command to reflect it across the y-axis....that would mean not to the bottom but to the side....so it would reflect to the quadrent to right of the shape so the 1st quadrent.....Next we are given to reflect it across the x-axis now that would mean over the horizontal line so we would reflect it down....so it would go from the 1st quadrent to the quadrent to the bottom which is the 4th one....Next we are told to rotate it 180 degrees....Now when rotating 180 degrees in which ever quadrent it is it will always go the the quadrent diagonally which is / or \ so in this case our shape right now is in the 4th quardrant so it would reflect to the 2nd quadrant once again and land on itself....

Answer 33

o....

Answer 34

No I didn't just typing this out ;)

Answer 35

yeah this would be easier if i knew how to rotate -_- 180

Answer 36

can i ask you another question

Answer 37

I actually got to go...got some physic work to do..sorry :(

Answer 38

awww its okay bye scientist ;)

Answer 39

But if you see me on just tag me in your question and ill come as soon as I can :)

Answer 40

isnt physics like extremely hard

Answer 41

like when i look at it i start to blur out

Answer 42

:P

Answer 43

Well right now its quite easy but i bet itll get hard xD I like math and space more :)

Answer 44

i want to become a surgeon is physic required do you know?!

Answer 45

I dont think so....probably does

Answer 46

okay shoo shoo go do your homework or whatever you need to do

Answer 47

:)

Answer 48

xD alrighty byee
