Answer: -a dilation followed by a translation
-a dilation followed by a reflection
-a reflection followed by a dilation
-a rotation followed by a dilation
Explanation:
A rigid transformation is a kind of transformation which does not affect the size of the shape.They produces congruent images.There are four kinds of rigid motions: 1) translation 2) reflection 3) rotation 4) glide reflection.
On the other hand a dilation is a transformation that creates an image that is the exactly same shape as the original, but have a different size.
Thus dilation does not create congruent images.
Therefore any sequence of transformations which has dilation will not result in an image that is similar and non-congruent to the pre-image.
