Use the image to answer the question.
An illustration of a coordinate plane with four quadrants shows the x and y axes extending from negative 10 to 10 in increments of 1. Three triangles are plotted on the graph. The triangle upper A upper B upper C has its vertices marked with closed points at upper A left parenthesis 2 comma negative 2 right parenthesis, upper B left parenthesis 2 comma negative 4 right parenthesis, and upper C left parenthesis 5 comma negative 4 right parenthesis. The second triangle, placed in the second quadrant, has its vertices marked with closed points at left parenthesis negative 3 comma 6 right parenthesis, left parenthesis negative 5 comma 6 right parenthesis, and left parenthesis negative 5 comma 3 right parenthesis. The third triangle, placed in the third quadrant, has its vertices marked with closed points at left parenthesis negative 2 comma negative 2 right parenthesis, left parenthesis negative 4 comma negative 2 right parenthesis, and left parenthesis negative 4 comma negative 5 right parenthesis.

To determine the sequence of transformations that proves the congruence of the triangles shown in the coordinate plane, we need to analyze the vertices of the triangles involved.
1. **Triangle \(ABC\)** has vertices \(A(2, -2)\), \(B(2, -4)\), and \(C(5, -4)\).
2. **Triangle \(DEF\)** has vertices \(D(-3, 6)\), \(E(-5, 6)\), and \(F(-5, 3)\).
3. **Triangle \(GHI\)** has vertices \(G(-2, -2)\), \(H(-4, -2)\), and \(I(-4, -5)\).
From the arrows in the diagram:
- The arrows indicate that \(G(-2, -2)\) moves to \(D(-3, 6)\),
- \(H(-4, -2)\) moves to \(E(-5, 6)\),
- \(I(-4, -5)\) moves to \(F(-5, 3)\).
To determine the transformations, we need to identify the nature of rotation and whether any translations have occurred:
### Step 1: Analyzing the Rotation
The triangles \(ABC\) and \(DEF\) share the height of the triangles \(AB\) and \(DE\) (both triangles are right triangles), and we check the orientation.
To find the angle of rotation:
- The points change from \( (2, -2) \) to \( (-3, 6) \) suggests that we calculate the angle of rotation from point \(A\) (i.e.,) from the positive x-axis.
### Step 2: Finding the Translation
Finding the vector for translation after the rotation:
- Determine how much \(D(-3, 6)\) translates concerning \(A(2, -2)\).
### Conclusion
Combining these transformations:
1. The triangles are rotated a certain number of degrees clockwise around the origin.
2. The triangles then undergo translation along the vector that moves \(A\) to \(D\).
Thus, the final answer to the transformation sequence needed to prove the congruence of triangles would typically be expressed something like:
Rotation of 180 degrees clockwise about the origin, then translation of (____).
You’ll need to input the exact numerical transformation for the translation based on the observed movements on the graph (based on the analysis).
