**Title: Reflections of Quadrilaterals**

**Objective:**
Understand how to reflect a quadrilateral across a given line and visualize the transformation.

**Instructions:**
Plot the image of quadrilateral \(ABCD\) under a reflection across line \(\ell\).

**Graph Description:**

1. **Initial Quadrilateral \(ABCD\)**:
   - The quadrilateral \(ABCD\) is plotted in a Cartesian coordinate system with point coordinates accurately placed on a grid.
   - Points \(A\), \(B\), \(C\), and \(D\) form quadrilateral \(ABCD\) which is displayed using a blue outline.

2. **Line of Reflection (\(\ell\))**:
   - Line \(\ell\) is a vertical line, prominently marked in black, and positioned to the right of quadrilateral \(ABCD\).
   - The line \(\ell\) acts as the axis of reflection and is extended vertically across the grid.

3. **Reflected Quadrilateral**:
   - A reflection of quadrilateral \(ABCD\) is shown on the other side of line \(\ell\).
   - The reflected quadrilateral is displayed using a green outline, with each corresponding point (\(A'\), \(B'\), \(C'\), \(D'\)) matching the coordinates perfectly. 
   - Distance from the original points to the line \(\ell\) is mirrored precisely on the other side.

**Reflection Process**:
To reflect a point across a vertical line \(\ell\), you must:

   1. Measure the horizontal distance from the point to the line \(\ell\).
   2. Move the point the same distance on the opposite side of the line \(\ell\).

This process is repeated for each point \(A\), \(B\), \(C\), and \(D\) of the quadrilateral, creating the reflected quadrilateral.

**Key Points to Remember**:

- Reflections produce a mirror image of the shape across the line.
- The perpendicular distance of each point from the line remains constant.
- The reflected shape is congruent to the original shape.

This visual demonstration helps in understanding the principles of reflection in geometry, reinforcing the concept that reflective symmetry displays congruent shapes across an axis.
