the transformation is a rotation
true or false

Answer:
FALSE
Step-by-step explanation:
The transformation is a reflection across the line x=1.
In order from shortest to longest, the sides of the left triangle are in counterclockwise order. In the right triangle, they are in clockwise order. This indicates a reflection. A rotation does not change the (CW/CCW) orientation of the triangle.
It is False that the transformation is a rotation.
