Dana draws an F on a clear piece of plastic. Which transformation would fail to preserve congruence?
Looking at the F through a magnifying glass.
Moving the piece of plastic down and to the left
Turning the piece of plastic over
Turning the piece of plastic upside down
Looking at the F through a magnifying glass would fail to preserve congruence. The other three transformations (moving, turning over, and turning upside down) would preserve the shape of the F.
