Question

If parallelogram JKLM is rotated 270° clockwise around the origin, what are the coordinates of the endpoints of the side congruent to side KL in the image parallelogram?

K'(-4, -6); L'(3, -3)

K'(-6, -4); L'(-3, -3)

K'(6, 4); L'(3, 3)

K'(-4, 6); L'(-3, -3)

Answer 1

2.If pentagon ABCDE is rotated 180° around the origin to create pentagon A'B'C'D'E', what is the ordered pair of point A'?

(2, -4)

(-4, -2)

(-2, -4)

(4, 2)

Answer 2

For your pentagon..
180 degrees rotation is
(A,B) ==> (-A,-B)
so
(-2,4) -- > (2,-4)

Answer 3

Now, for your 270 degree rotation.
(x,y) becomes (-y,x)
K - (-5,6) becomes (-6,-5)
L - (-3,3) becomes (-3,-3)

Answer 4

im really trying...i just dont understand this at all, thanks though ...

Answer 5

Yo jon why did you copy that from this ?

Answer 6

Don't plagiarize...

Answer 7

lololol

Answer 8

anyways bri, do you understand the rotation formulas?
for 180 degrees rotation (x,y) becomes ( -x,-y)
for 270 degrees rotation (x,y) becomes ( -y,x)

Answer 9

uhm...im still sooo confused, i appreciate the help... so for the first one i got...c And the second one i got b? is that right ?

Answer 10

OHH!! that makes more since, i didnt really understand the formula!

Answer 11

The first one is B. (-6,-4) , (-3,-3)

Answer 12

Sorry I thought the y original x coordinate was a 5.

Answer 13

K - (-4,6) becomes (-6,-4)*
L - (-3,3) becomes (-3,-3)

Answer 14

There, since shamil is being a wingspan, let him hepl you!

Answer 15

thanks for your help jon!

Answer 16

Cuz you tried jon:P

Answer 17

wait are you sure that one is B?

Answer 18

Yes.

Answer 19

alright thanks ! and for the next one, i rotated it, i think right, i got c ? is that right

Answer 20

Point A is at (-2,4)
what is (-x,-y) ?

Answer 21

lul

Answer 22

(2,-4) @brianna98bri is your answer..

Answer 23

thanks...im starting to get it, thanks for being patient !
