# Rigid transformations: preserved properties

## Problem

Quadrilateral A, prime, B, prime, C, prime, D, prime is the result of reflecting quadrilateral A, B, C, D across the line ell.
A coordinate plane. The x- and y-axes both scale by one. A quadrilateral A B C D is in the first quadrant. A line of reflection starts at zero, zero and passes through Point C of the quadrilateral.
Select all of the correct statements about the unchanged properties of quadrilateral A, B, C, D and quadrilateral A, prime, B, prime, C, prime, D, prime.
