which of the following transformations does not result in a congruent figure?

Question

a. dilation

b. rotation

c. reflection

s. translation

Answer 1

Congruent figures are the same shape and the same size. The only choice that involves changing the size of a figure is letter a) dilation and as a result, creates two figures that are NOT congruent.

The other three choices merely "move" a shape to a new location (i.e. rotated, translated, or reflected) and result in a congruent figure.

Answer 2

A. Dilation

All other transformation listed are isometric, they do not change the size and shape of the figure.
