( properties of rotations 8th grade)

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

answer: bearing in mind that a rectangle has a perimeter of length + length + width + width.

step-by-step explanation:

p = perimeter

l = length

x=width

p = 2l + 2x

p = 2(l+x)     < ==== perimeter of the base of the box.
