Triangle [tex]\(XYZ\)[/tex] has vertices [tex]\(X(0,0)\)[/tex], [tex]\(Y(0,-2)\)[/tex], and [tex]\(Z(-2, 2)\)[/tex]. It is rotated to create the image triangle [tex]\(X'(0,0)\)[/tex], [tex]\(Y'(2,0)\)[/tex], and [tex]\(Z'(2,-2)\)[/tex].

Which rules could describe the rotation? Select two options:

A. [tex]\(R_{0,90^{\circ}}\)[/tex]

B. [tex]\(R_{0,180^{\circ}}\)[/tex]

C. [tex]\(R_{0,270^{\circ}}\)[/tex]

D. [tex]\((x, y) \rightarrow(-y, x)\)[/tex]

E. [tex]\((x, y) \rightarrow(y,-x)\)[/tex]

Given the vertices of triangle [tex]\(XYZ\)[/tex] as [tex]\(X(0,0)\)[/tex], [tex]\(Y(0,-2)\)[/tex], and [tex]\(Z(-2,2)\)[/tex], and the vertices of the image triangle [tex]\(X^{\prime}(0,0)\)[/tex], [tex]\(Y^{\prime}(2,0)\)[/tex], and [tex]\(Z^{\prime}(2,-2)\)[/tex], we need to determine which rotations might transform [tex]\(XYZ\)[/tex] to [tex]\(X^{\prime}Y^{\prime}Z^{\prime}\)[/tex].

We are provided several options:
1. [tex]\(R_{0,90^{\circ}}\)[/tex]
2. [tex]\(R_{0,180^{\circ}}\)[/tex]
3. [tex]\(R_{0,270^{\circ}}\)[/tex]
4. [tex]\((x, y) \rightarrow (-y, x)\)[/tex]
5. [tex]\((x, y) \rightarrow (y, -x)\)[/tex]

Step-by-Step Analysis:

1. Test [tex]\(R_{0, 90^{\circ}}\)[/tex] or [tex]\((x, y) \rightarrow (-y, x)\)[/tex]:
- [tex]\(X(0,0) \rightarrow (-0, 0) = (0, 0)\)[/tex] which matches [tex]\(X^{\prime}(0, 0)\)[/tex].
- [tex]\(Y(0, -2) \rightarrow (2, 0)\)[/tex] which matches [tex]\(Y^{\prime}(2, 0)\)[/tex].
- [tex]\(Z(-2, 2) \rightarrow (-2, -2)\)[/tex], but [tex]\(Z^{\prime} is (2, -2)\)[/tex], so this transformation does not match.

2. Test [tex]\(R_{0, 180^{\circ}}\)[/tex] or [tex]\((x, y) \rightarrow (-x, -y)\)[/tex]:
- [tex]\(X(0,0) \rightarrow (0, 0)\)[/tex] which matches [tex]\(X^{\prime}(0, 0)\)[/tex].
- [tex]\(Y(0, -2) \rightarrow (0, 2)\)[/tex] which does not match [tex]\(Y^{\prime}(2, 0)\)[/tex].
- Therefore, this transformation does not match.

3. Test [tex]\(R_{0, 270^{\circ}}\)[/tex] or [tex]\((x, y) \rightarrow (y, -x)\)[/tex]:
- [tex]\(X(0,0) \rightarrow (0, 0)\)[/tex] which matches [tex]\(X^{\prime}(0, 0)\)[/tex].
- [tex]\(Y(0, -2) \rightarrow (-2, 0)\)[/tex] which does not match [tex]\(Y^{\prime}(2, 0)\)[/tex].
- Therefore, this transformation does not match.

Having checked all possible rotations and their coordinate transformation rules, we see that no combination of the listed rotations can transform triangle [tex]\(XYZ\)[/tex] to triangle [tex]\(X^{\prime}Y^{\prime}Z^{\prime}\)[/tex] correctly.

Thus, the conclusion is:

No transformation among the given options matches the criteria to transform the triangle correctly. Therefore, the answer is:
[tex]\[[]\][/tex]
