If triangle ABC is reflected over the y‐axis, reflected over the x‐axis, and rotated 180 degrees, where will point A' lie? (−1, 2)
(−2, 1) I think it's this answer but i'm not sure
(1, −2)
(2, −1)

The location of A' is .

Step-by-step explanation:

We know the location of A in rectangular form and must transform it into polar form, which is represented by magnitude (), dimensionless, and direction (), measured in sexagesimal degrees. Let suppose that rotation is counterclockwise and around the origin:

Magnitude

(1)

Direction

(2)

The location of A' is determined by the following expression:

If we know that , then the location of A' is:

The location of A' is .

"image"

step-by-step explanation:

in most of these problems, the notation is that the point with a "prime" is the image of the point without. that is, b' is the image of b.

here, there is no dilation or reflection. there is simply translation (with no direction shown). which figure you call the "preimage" and which one you call the "image" is up to you. as a matter of convention, the naming is as described above.
