Answer:

The transformation which do not describe a rigid motion transformation is:

Option: C

C. dilating a figure by a scale factor of 1/4

Explanation:

Rigid motion transformation is a transformation in which the shape and size of the figure is preserved i.e. it remains the same.

A)

Translating a figure 5 units right.

We know that in the translation transformation the shape and size of the figure remains the same only the location of points are changed.

B)

Rotating a figure 90 degrees.

In rotation the shape and size is preserved.

Hence it is a rigid transformation.

C)

dilating a figure by a scale factor of 1/4

This is not a rigid transformation because the size of the figure is changed.

since the scale factor is less than 1.

Hence, the transformation is a reduction of the original figure.

D)

reflecting a figure across the x-axis.

The reflection is also a rigid transformation.

since it preserves the shape and size of the object.
