Question

Under which transformation can the image be a different size than the original figure

Answer 1

The four main types of transformations are reflection, rotation, translation, ans dilation. All of these transformation retain their original size except for dilations.
Hope this helps.

Answer 2

The figure can be different size in dilation.

Explanation:

Transformations are defined as certain ways like transformation, reflection etc. to manipulate the shape of any figure.

The original shape is called the pre-image and we get a final shape under the transformation.

So, the three transformations like translation, reflection and rotation retain the same size of the final image as the pre image.

Only dilation is a transformation that enlarges or reduces the size of the object.
