To determine which transformations will result in a figure that is similar but not congruent, we need to analyze each transformation:
1. **A dilation with a scale factor of 0.75**: This transformation changes the size of the figure but maintains the shape. Since the size is different, the figure will be similar but not congruent. **(Select this option)**
2. **A 180 degree rotation**: This transformation preserves the size and shape of the figure. It merely changes the orientation, so the figure remains congruent. **(Do not select this option)**
3. **A reflection across a horizontal line**: Like the rotation, a reflection also preserves size and shape, maintaining congruence. **(Do not select this option)**
4. **A translation to the right**: This transformation also keeps the size and shape of the figure unchanged, maintaining congruence. **(Do not select this option)**
Based on this analysis, the only transformation that produces a figure that is similar but not congruent is:
- **A dilation with a scale factor of 0.75**.
