Does the size and shape of the original figure change when you transform it (using reflections, rotations, or translations)?

• yes, the size changes
• yes, the shape changes
• yes, the size and shape change
• no, the size and shape remain the same

The point Z with coordinates (2, -3) is rotated about the origin to Z'(-3, -2). How many degrees was the point rotated
and in what direction?

• 90 degrees clockwise
• 90 degrees counterclockwise
• 180 degrees
• 270 degrees clockwise

Use the mapping function (x,y) -> (x+7, y+1) to translate ΔFGY.

• right 7, down 1
• left 7, up 1
• right 7, up 1
• left 7, down 1

Rotate ΔJVK 270˚ counterclockwise. What is the rule?

• (y, x)
• (y, -x)
• (-y, x)
• (-x, -y)

Write the mapping function for the translation below.

• (x + 1, y - 1)
• (x - 1, y - 2)
• (x - 2, y + 1)
• (x + 2, y - 1)
