When a polygon reflects onto itself during a transformation, the **line of reflection** must be an **axis of symmetry** for that polygon. This means that the line of symmetry divides the polygon into two parts that are mirror images of each other.

**Symmetry** ensures that every point on one side of the line of reflection has a corresponding point directly opposite it on the other side, maintaining the shape and size of the polygon after the reflection. Therefore, the line of reflection required for the polygon to map onto itself must align perfectly with one of its symmetry axes.

**Example:**  
Consider a regular hexagon, which has multiple lines of symmetry. If you choose any one of these symmetry lines as the line of reflection, reflecting the hexagon across that line will map the hexagon onto itself, demonstrating its symmetrical property.

**Key Points:**
- The **line of reflection** must be a **symmetry axis** of the polygon.
- **Symmetry** ensures that the polygon maps onto itself after reflection.
- Each point on the polygon has a mirror counterpart across the symmetry line.

Understanding the relationship between symmetry and reflection lines is fundamental in studying geometric transformations and the properties of shapes.
The line of reflection must be a symmetry axis of the polygon, ensuring that the polygon maps onto itself after reflection.
