1. Is T(z) =-z a translation, dilation, rotation, or none of the above?

1 Quadrilateral W'X'YZ'is a reflection of quadrilateral WXYZ across the x-axis. Quadrilateral W"X"Y"Z" is a 180° rotation of quadrilateral WXYZ counterclockwise about the origin. 9. W. -8 -6 -4 -2 6 Z" -2 Y" -8 X' Which of the following statements is true? A Orientation of the vertices is preserved for quadrilateral W'X'YZ'; therefore, only reflections across the x-axis preserve orientation of the vertices. B Orientation of the vertices is preserved for quadrilateral W"X"Y'Z"; therefore, only 180° rotations counterclockwise about the origin preserve orientation of the vertices. C Orientation of the vertices is not preserved for quadrilateral W"X"Y"Z"; therefore, all rotations do not preserve orientation of the vertices. D Orientation of the vertices is not preserved for quadrilateral W'XYZ; therefore, all reflections do not preserve orientation of the vertices. D

4. If N'(-1,-5) is the image of N(1, -5) after a transformation, which transformation could have occurred? A. A reflection in the x-axis. B. A reflection in the y-axis. C. A 90° counterclockwise rotation about the origin. D. A 180° rotation about the origin. Gina Wilsonnings Algebra®, LLC), 2021
