One vertex of a triangle is located at [tex]\((0, 5)\)[/tex] on a coordinate grid. After a transformation, the vertex is located at [tex]\((5, 0)\)[/tex].

Which transformations could have taken place? 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]\(R_{0, -90^{\circ}}\)[/tex]

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



Answer :

Certainly! Let's determine which transformations could result in the vertex of the triangle moving from [tex]\((0,5)\)[/tex] to [tex]\((5,0)\)[/tex].

### Transformation Descriptions:
1. [tex]\(R_{0,90^{\circ}}\)[/tex]: A rotation by [tex]\(90^\circ\)[/tex] counterclockwise around the origin.
2. [tex]\(R_{0,180^{\circ}}\)[/tex]: A rotation by [tex]\(180^\circ\)[/tex] around the origin.
3. [tex]\(R_{0,270^{\circ}}\)[/tex]: A rotation by [tex]\(270^\circ\)[/tex] counterclockwise around the origin.
4. [tex]\(R_{0,-90^{\circ}}\)[/tex]: A rotation by [tex]\(90^\circ\)[/tex] clockwise around the origin.
5. [tex]\(R_{0,-180^{\circ}}\)[/tex]: A rotation by [tex]\(180^\circ\)[/tex] clockwise around the origin.

### Applying Transformations:
1. [tex]\(R_{0,90^{\circ}}\)[/tex]: Rotation by [tex]\(90^\circ\)[/tex] counterclockwise
- Starting point: [tex]\((0,5)\)[/tex]
- Transformation to: [tex]\((-5,0)\)[/tex]
- Result: [tex]\((-5,0)\)[/tex], which is not [tex]\((5,0)\)[/tex].

2. [tex]\(R_{0,180^{\circ}}\)[/tex]: Rotation by [tex]\(180^\circ\)[/tex]
- Starting point: [tex]\((0,5)\)[/tex]
- Transformation to: [tex]\((0,-5)\)[/tex]
- Result: [tex]\((0,-5)\)[/tex], which is not [tex]\((5,0)\)[/tex].

3. [tex]\(R_{0,270^{\circ}}\)[/tex]: Rotation by [tex]\(270^\circ\)[/tex] counterclockwise
- Starting point: [tex]\((0,5)\)[/tex]
- Transformation to: [tex]\((5,0)\)[/tex]
- Result: [tex]\((5,0)\)[/tex], which matches the transformed coordinates.

4. [tex]\(R_{0,-90^{\circ}}\)[/tex]: Rotation by [tex]\(90^\circ\)[/tex] clockwise
- Starting point: [tex]\((0,5)\)[/tex]
- Transformation to: [tex]\((5,0)\)[/tex]
- Result: [tex]\((5,0)\)[/tex], which matches the transformed coordinates.

5. [tex]\(R_{0,-180^{\circ}}\)[/tex]: Rotation by [tex]\(180^\circ\)[/tex] clockwise
- Starting point: [tex]\((0,5)\)[/tex]
- Transformation to: [tex]\((0,-5)\)[/tex]
- Result: [tex]\((0,-5)\)[/tex], which is not [tex]\((5,0)\)[/tex].

### Conclusion:
The valid transformations are [tex]\(R_{0,270^{\circ}}\)[/tex] and [tex]\(R_{0,-90^{\circ}}\)[/tex], as they both result in the vertex moving from [tex]\((0,5)\)[/tex] to [tex]\((5,0)\)[/tex].

Hence, the correct options are:
- [tex]\(R_{0,270^{\circ}}\)[/tex]
- [tex]\(R_{0,-90^{\circ}}\)[/tex]
