Question

Which type of transformation does not necessarily result in the image being congruent to the preimage?

dilation
reflection
rotation
translation

Answer 1

Hint: 3 of those are considered rigid transformations

Answer 2

C?

Answer 3

does a rotation change the shape and size of the object being rotated?

Answer 4

no, so its dilation

Answer 5

good, a rotation is a rigid transformation...size and shape doesn't change

Answer 6

and a dilation isn't rigid, so A is the correct answer
