To determine the type of translation applied to quadrilateral ABCD, we need additional information about the quadrilateral, such as its coordinates before and after the translation, a description of the translation (e.g., how far and in which direction it was moved), or a diagram representing the translation.
In general, a translation in geometry involves moving a shape from one position to another without changing its shape, size, or orientation. If you can provide specific details about the coordinates or the nature of the transformation, I can help you identify the translation applied to quadrilateral ABCD.
