Question

Just One More Please Lol @ganeshie8

What set of rotations would carry parallelogram ABCD onto itself?

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

reflect over the y-axis, reflect over the x-axis, rotate 180�

Answer 1

I picked Option B At first but I Know Something Is Wrong With That.

Answer 2

Again the 1/2 are degrees

Answer 3

got that :)

Answer 4

lets look at last option

Answer 5

Okay :)

Answer 6

reflect over the y-axis, reflect over the x-axis, rotate 180�

Answer 7

take any point : (x, y)

reflect over y-axis :
(x, y) -> ??

Answer 8

can u tell me how it changes ?

Answer 9

Ok it would go y,x since we flipped it

Answer 10

nope, u need to memorize below :

reflection in x-axis :
(x, y) -> (x, -y)

reflection in y-axis :
(x, y) -> (-x, y)

rotating 180 degrees :
(x, y) -> (-x, -y)

Answer 11

okay ?

Answer 12

refer to them and can u tell me wat u wud get after doing first transformation below :

reflect over the y-axis, reflect over the x-axis, rotate 180�

Answer 13

Eep , I was going to say that the x would turn into a negative but idk what made me think that was wrong >.<

Answer 14

hahah happens.. these are tricky lol

Answer 15

Lol

Answer 16

(x, y)

reflect over y-axis :
(x, y) -> (-x, y)

reflect over x-axis :
(-x, y) -> (-x, -y)

rotate 180 degrees :
(-x, -y) -> (x, y)

Answer 17

Ok this is looking more clear

Answer 18

so u got back ur point, wat does that mean ?

Answer 19

that option D would carry parallelogram ABCD onto itself

Answer 20

yep !

Answer 21

Thank You You're The Best!!!!

Answer 22

np, u wlc :))
