Exercise 2 Page 577

An isometry is a transformation that preserves distance, or length.

No, see solution.

Practice makes perfect

Recall that an isometry is a transformation that preserves distance. Let's examine the diagram below.

We see that the distances between the vertices of the image are not the same as the corresponding distances in the preimage. Therefore, the distance is not preserved, which implies that it is not an isometry.
