Answer:
Teagan is correct because the unshaded rectangle is smaller than the shaded rectangle.
Explanation:
Translation in geometry describes a function that moves an object a certain distance without any alteration to the object in any way. Every point of the object must be moved in the same direction and through the same distance. While dilation is a transformation that produces an image of a given object but of different size. It requires a scale factor and a fixed point in the plane called the center of the dilation.
Therefore comparing the two shapes, the transformation is dilation. So, Teagan is correct because the unshaded rectangle is smaller than the shaded rectangle.
