Transformation Review

What is a translation in geometry?

• A translation in geometry is a transformation that moves every point of a figure the same distance in the same direction.

• A translation in geometry is a transformation that moves every point of a figure a different distance in different directions.

• A translation in geometry is a transformation that moves every point of a figure a different distance in the same direction.

• A translation in geometry is a transformation that rotates every point of a figure the same distance in the same direction.
