### Transformation and Congruence in Geometry

#### Problem:
**22. Describe a sequence of transformations that justify ΔDEF ≅ ΔD'E'F'. All rotations are centered at the origin.**

#### Options:
A. Two rotations 90° clockwise  
B. A rotation 90° clockwise and a reflection over the y-axis  
C. A rotation 90° counterclockwise and a reflection over the x-axis  
D. A rotation 90° clockwise and a translation left 10 units  

#### Explanation of the Graph:
The graph depicts two triangles, ΔDEF and ΔD'E'F', on a coordinate plane.  
- Triangle ΔDEF has vertices located at:
  - D(4, 1)
  - E(4, 5)
  - F(7, 1)
  
- Triangle ΔD'E'F' has vertices located at:
  - D'(-1, 4)
  - E'(-5, 4)
  - F'(-1, 7)

A sequence of transformations involves changing a figure's position or orientation without altering its shape and size. The problem requires identifying the sequence of such transformations that can show that ΔDEF is congruent to ΔD'E'F'. 

#### Diagram Analysis:
The diagram should help us visualize how one triangle can be transformed into another using rotations, reflections, or translations.

1. **Option A: Two rotations 90° clockwise**
   - First rotation: Moving ΔDEF 90° clockwise around the origin.
   - Second rotation: Moving the resulting position another 90° clockwise around the origin.

2. **Option B: A rotation 90° clockwise and a reflection over the y-axis**
   - A single 90° clockwise rotation might reorient the triangle, then reflecting it over the y-axis to possibly match the position of ΔD'E'F'.

3. **Option C**: A rotation 90° counterclockwise and a reflection over the x-axis
   - A single 90° counterclockwise rotation followed by a reflection over the x-axis could also position the triangle similarly.

4. **Option D: A rotation 90° clockwise and a translation left 10 units**
   - A single 90° clockwise rotation followed by shifting it left 10 units on the coordinate plane may place the triangle in a congruent position.

The goal is to understand which transformation shows ΔDEF can be mapped precisely onto ΔD'E
