Question
**Reflection and Translation of Triangle PQR**

Triangle \( PQR \) is reflected across the line \( y = 0 \). The image is then translated 5 units to the right, resulting in \( \triangle STU \).

**Coordinate Plane Explanation:**

- **Triangle \( PQR \):**
  - Vertex \( P \) is located at approximately (-5, 2).
  - Vertex \( Q \) is located at approximately (-3, 6).
  - Vertex \( R \) is located at approximately (-2, 3).

- **Reflection Process:**
  - The vertices of triangle \( PQR \) are reflected over the x-axis (line \( y = 0 \)).
  - Reflected coordinates are:
    - \( P' \) at (-5, -2)
    - \( Q' \) at (-3, -6)
    - \( R' \) at (-2, -3)

- **Translation Process:**
  - Each point of the reflected triangle is moved 5 units to the right.
  - Final coordinates are:
    - \( S \) at (0, -2)
    - \( T \) at (2, -6)
    - \( U \) at (3, -3)

**Multiple Choice Statements:**

A. \( PQ = ST \)

B. \( PQ = TU \)

C. \( m \angle R = m \angle U \)

D. \( m \angle P = m \angle U \)

Select all statements that apply after the reflection and translation processes have been completed.

**Further Analysis:**

- Make sure to check the lengths and angles of the subsequent triangle \( \triangle STU \) to verify the equality of sides or angles as per the given statements.
