Introduction

Transformations in coordinate geometry refer to the changes that can be applied to the coordinates of a point or a shape. These changes can be translations, rotations, reflections, or dilations. In this article, we will explore the possible transformations that could have taken place to move a vertex of a triangle from ${$ (0, 5)$}$ to ${$ (5, 0)$}$.

What are Transformations?

Transformations are changes that can be applied to the coordinates of a point or a shape. These changes can be translations, rotations, reflections, or dilations. Translations involve moving a point or shape from one location to another without changing its size or orientation. Rotations involve turning a point or shape around a fixed point or axis. Reflections involve flipping a point or shape over a line or axis. Dilations involve changing the size of a point or shape.

Possible Transformations

Given that the vertex of the triangle is located at ${$ (0, 5)$}$ and after a transformation, it is located at ${$ (5, 0)$}$, we need to determine the possible transformations that could have taken place. Let's consider the following options:

Option A: Rotation of 90 degrees

A rotation of 90 degrees can be represented by the transformation ${$ R_{0,90}$}$. This transformation involves rotating a point or shape around the origin (0, 0) by 90 degrees. If we apply this transformation to the vertex ${$ (0, 5)$}$, we get:

${$ (0, 5) \rightarrow (5, 0)$]

This transformation matches the given coordinates, so it is a possible option.

Option B: Reflection over the x-axis

A reflection over the x-axis can be represented by the transformation [ $R_{x}\$}$ . This transformation involves flipping a point or shape over the x-axis. If we apply this transformation to the vertex ${$ (0, 5)$}$, we get:

${$ (0, 5) \rightarrow (0, -5)$]

However, this transformation does not match the given coordinates. Therefore, it is not a possible option.

Option C: Reflection over the y-axis

A reflection over the y-axis can be represented by the transformation [ $R_{y}\$}$ . This transformation involves flipping a point or shape over the y-axis. If we apply this transformation to the vertex ${$ (0, 5)$}$, we get:

${$ (0, 5) \rightarrow (0, 5)$]

This transformation does not change the coordinates, so it is not a possible option.

Option D: Translation

A translation involves moving a point or shape from one location to another without changing its size or orientation. If we apply a translation to the vertex [ $(0, 5)\$}$ , we get:

${$ (0, 5) \rightarrow (x, y)$]

where [$(x, y)$] are the new coordinates. This transformation does not match the given coordinates, so it is not a possible option.

Option E: Dilation

A dilation involves changing the size of a point or shape. If we apply a dilation to the vertex [ $(0, 5)\$}$ , we get:

${$ (0, 5) \rightarrow (x, y)$]

where [$(x, y)$] are the new coordinates. This transformation does not match the given coordinates, so it is not a possible option.

Conclusion

In conclusion, the possible transformations that could have taken place to move a vertex of a triangle from [ $(0, 5)\$}$ to ${$ (5, 0)$}$ are:

Rotation of 90 degrees: This transformation involves rotating a point or shape around the origin (0, 0) by 90 degrees.
Reflection over the x-axis: This transformation involves flipping a point or shape over the x-axis. However, this transformation does not match the given coordinates, so it is not a possible option.

Final Answer

The final answer is:

Option A: Rotation of 90 degrees
Option B: Reflection over the x-axis (not a possible option)
