Question

6
which of the following is not a rigid motion transformation?
a. dilation
b. reflection
c. rotation
d. translation

Explanation:

Rigid motion transformations (isometries) preserve the shape and size (distance and angle measures) of a figure. Reflection, rotation, and translation are rigid motions as they don't change the figure's dimensions. Dilation changes the size (scales the figure) by a scale factor, so it's not a rigid motion.

Answer:

A. Dilation
