Translation of Figures Quiz

True or False: The perimeter of rectangle ABCD is equal to the perimeter of rectangle A'B'C'D'. Explain how you can determine the answer without calculating the exact perimeter of either rectangle.

• True

• False

• Cannot be determined

• None of the above

Write the arrow notation to describe the translation of figure ABCD 6 units down and 2 units left.

• (x, y) → (x + 2, y - 6)

• (x, y) → (x - 2, y + 6)

• (x, y) → (x - 2, y - 6)

• (x, y) → (x + 2, y + 6)

If a figure is translated 6 units down and 2 units left, what happens to the coordinates of a point (x, y) on the figure?

• The new coordinates are (x + 2, y + 6)

• The new coordinates are (x - 2, y - 6)

• The new coordinates are (x - 6, y - 2)

• The new coordinates are (x + 6, y + 2)
