To determine which transformation could show that corners 1 and 2 are congruent, we need to consider how each option may affect the positions of the corners in relation to each other.

1. **Rotation 180 degrees clockwise**: This transformation would rotate the figure, potentially moving corners to different positions. However, without a specific diagram or information about the corners' positions in relation to each other, it's hard to definitively say this would show congruence directly.

2. **Reflection across line m**: A reflection across a line would create a mirror image, which is often used to show congruence between two figures or segments. If corners 1 and 2 are positioned such that one can be reflected over line m to land on the other, then this transformation would demonstrate their congruence.

3. **Reflection across line n**: Similar to line m, a reflection across line n could also show congruence if it is positioned appropriately.

4. **Translation to the right**: A translation moves a figure without changing its shape or orientation. While this would maintain congruence, it would not be the best choice to show that two specific corners are congruent unless they were initially aligned.

From these options, the best transformations to demonstrate that corners 1 and 2 are congruent would be the reflections across line m or line n. Since the question does not provide a specific diagram, we cannot pinpoint one specifically without additional information. However, **either reflection option (across line m or line n)** is the most likely to show congruence effectively.

If you have access to a specific diagram showing the positions of corners 1 and 2, you could choose the reflection line that correctly connects them. In summary, if congruence is to be shown, you would likely choose either:

- **Reflection across line m**
or
- **Reflection across line n**

for congruence between corners 1 and 2, based on their relative positions.
