**Question:**

Select all of the following transformations that would map \( \triangle CDE \) to \( \triangle TSR \).

- □ A reflection over the x-axis
- □ A reflection over the line \( x = 0.5 \)
- □ A translation of \((x, y) \to (x + 5, y)\)
- □ A rotation of \(90^\circ\) counterclockwise about the point \((5, 5)\)
- □ A reflection over the line \( x = -4 \) and a translation of \((x, y) \to (x + 2, y)\)

The image represents the framework for the roof of a house. It displays a geometric structure on a coordinate grid, with axes labeled \(x\) and \(y\).

### Description:

- **Axes and Grid:** The coordinate grid has labels along the \(x\)-axis from \(-1\) to \(11\) and along the \(y\)-axis from \(-3\) to \(3\).
  
- **Framework Structure:** 
  - The roof comprises two main right triangles, marked in blue and red, meeting at a central peak above the \(x\)-axis.
  - The blue triangle is on the left, spanning from \(x = 0\) to \(x = 4\), peaking at point \(D\).
  - The red triangle is on the right, spanning from \(x = 7\) to \(x = 10\), peaking at point \(S\).

- **Key Points:**
  - **C** is at (0, 0).
  - **E** is at (4, 0), forming the base of the blue triangle.
  - **D** is at the midpoint of the blue triangle's slope.
  - **R** is at (7, 0), forming the base end of the red triangle.
  - **T** is at (10, 0).
  
- **Additional Details:**
  - The triangles have shaded areas with distinct colors: purple for the left and red for the right, emphasizing structural supports.
  - The \(y\)-axis has small numerical labels, indicating measurements up to \(\sim3\).

This diagram could be used to discuss architectural design, geometry in engineering, or trigonometric properties in an educational setting.
