Pentagon ABCDE is shown on the coordinate plane below.

Pentagon on coordinate plane with ordered pairs at A negative 2, 4, at B negative 6, 2, at C negative 5, negative 2, at D 1, negative 2, at E 2, 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 C'?

(-5, 2)

(5, 2)

(2, -5)

(-2, 5)

Answer 1

Any point (x,y) that is rotated 180 degrees about the origin will turn into (-x,-y)

Ex: (1,5) rotates 180 degrees about the origin to (-1,-5)

Answer 2

(5, 2)?

Answer 3

or just take the opposite of each coordinate in the preimage

Answer 4

am i correct?

Answer 5

Yes :D

Answer 6

thnx btw i got more

Answer 7

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

Parallelogram formed by ordered pairs A at negative 4, 1, B at negative 3, 2, C at 0, 2, D at negative 1, 1.

(-4,1)

(1,-1)

(1,1)

(-4,-1)

Answer 8

Youre welcome. ;) Just tag me anytime.

Answer 9

i did
did you get it?

Answer 10

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

Parallelogram formed by ordered pairs A at negative 4, 1, B at negative 3, 2, C at 0, 2, D at negative 1, 1.

(-4,1)

(1,-1)

(1,1)

(-4,-1)

Answer 11

can you do that one?

Answer 12

like i said

Any point (x,y) that is rotated 180 degrees about the origin will turn into (-x,-y)

Ex: (1,5) rotates 180 degrees about the origin to (-1,-5)

Answer 13

Its D

Answer 14

you only change th signs if you rotate 180 degrees
