Front

Rigid Transformations will always maintain and preserve ALL of the following EXCEPT: size and shape, angle measurements, location and orientation, area and perimeter, parallel lines.

Back

location and orientation

Front

Sequence of transformations for the image with prime symbols? Options: Reflect over the x-axis, translate (x+8,y); Reflect over the x-axis then translate (x+6, y); Reflect over the y-axis then (x+1, y+1); Translate down 4 (y-4) and to the right 5 (x+5)

Back

Reflect over the x-axis then translate (x+6, y)

Front

Sequence of transformations from A to A' to A"? Options: Reflect across the x-axis and then rotate 90 degrees clockwise around the origin, Rotate 90 degrees clockwise around the origin and then translate down, Reflect across the x-axis and then reflect across the y-axis, Translate up and then rotate 90 degrees counterclockwise about the origin.

Back

Translate up and then rotate 90 degrees counterclockwise about the origin.
