A. 1. a 90° clockwise rotation of ΔABC about the origin
2. a 180° clockwise rotation of the image about the origin
3. a 270° clockwise rotation of the image about the origin
B. 1. a reflection of ΔABC across the y-axis
2. a reflection of the image across the x-axis
3. a 90° counterclockwise rotation of the image about the origin
C. 1. a reflection of ΔABC across the y-axis
2. a reflection of the image across the x-axis
3. a reflection of the image across the y-axis
D. 1. a reflection of ΔABC across the line y = x
2. a reflection of the image across the x-axis
3. a reflection of the image across the y-axis
