What is preserved during a translation?

• Size and orientation

• Size, shape, and orientation

• Size and shape

• Orientation and shape

How many units to the right does the figure move in the given translation example?

• 4

• 5

• 6

• 7

What is the algebraic rule for the translation example provided?
