1. What is the unique about a rigid transformation?(2 points) Responses A rigid transformation is always with a square or triangle. A rigid transformation is always with a square or triangle. A rigid transformation changes sizes from the pre image to the new image. A rigid transformation changes sizes from the pre image to the new image. In a rigid transformation, the pre image and new image are congruent and the size does not change. In a rigid transformation, the pre image and new image are congruent and the size does not change.

In summary, the unique aspect of a rigid transformation is that it preserves size and shape, resulting in congruent pre-image and new image.
