C: The translation preserves side lengths and angles, but the vertical stretch does not preserve side lengths and angles of the preimage.
When we talk about the concept of translation in transformations, it means that the side lengths remain the same. This means the object is just moved from one place to another and the lengths are preserved.
However, when we stretch the polygon, it means we are increasing or decreasing at least one side length.
Thus, we can conclude that The translation preserves side lengths and angles, but the vertical stretch does not preserve side lengths and angles of the preimage.
