Dana draws an Fon a clear piece of plastic. Which transformation would fail to preserve congruence? (1 point)

looking at the F through a magnifying glass

turning the piece of plastic over

turning the piece of plastic upside down

moving the piece of plastic down and to the left

1 answer

To determine which transformation would fail to preserve congruence, we need to understand the nature of the transformations mentioned.

  • Looking at the F through a magnifying glass: This transformation changes the size of the F, making it larger, which does not preserve congruence.

  • Turning the piece of plastic over: This is a reflection, which does preserve congruence.

  • Turning the piece of plastic upside down: This is a rotation, which also preserves congruence.

  • Moving the piece of plastic down and to the left: This is a translation, which preserves congruence as well.

Based on this analysis, the transformation that would fail to preserve congruence is:
