Answer:
7:
A: This rotation can be described as a 90 degree rotation counterclockwise, or a 270 degree rotation clockwise about the point x = 1.
B: A'(3,1), B'(2,3), C'(-1,4)
8:
A: This rotation could be described as a 180 degree clockwise and counterclockwise rotation.
B: This translation can also be a reflection across the y-axis.
9: A reflection across the x or y-axis will preserve the figure.
10: The coordinates would be (-3,2).
11: 90 degrees clockwise
12: 180 degrees counterclockwise
13: 90 degrees counterclockwise
