Layla was able to map circle M onto circle N using a translation and a dilation. Layla concluded: “I was able to map M onto circle N using a sequence of rigid transformations, so the figures are congruent.” What error did Layla make in her conclusion.

Layla didn't only use rigid transformation, so the figure are not congruent.

Step-by-step explanation:

Rigid transformation is the procedure required to change the orientation of a given figure, without resizing it. Examples are: translation, reflection and rotations.

Since the mapping was achieved using a translation and dilation, there is an error in her conclusion.

Dilation is the process of resizing a given figure, but preserving its shape. It preserves the angles and the shape of the figure, but not the length of the sides.

Dilation is not an example of rigid transformation, therefore she did not only use rigid transformation to map circle M onto circle N.
