Question

which of the following transformations is considered a rigid transformation?
a. translation
b. dilation
c. scaling
d. distortion

Explanation:

A rigid transformation preserves the size and shape of a figure, meaning distances and angles remain unchanged. Translation shifts a figure without altering its size, shape, or orientation. Dilation, scaling, and distortion all change the size or shape of the figure, so they are not rigid transformations.

Answer:

a. Translation
