Front

A translation moves a shape (or points) _____________.

Back

the same distance and direction

Front

What is the original figure prior to a transformation called?

Back

Pre-image

Front

Which rule results in a translation of 2 units left and 3 units up? (x, y) → ?

Back

(x, y) → (x - 2, y + 3)

Front

In a dilation, what mathematical operation is used with the scale factor?

Back

multiplication

Front

What is a dilation in geometry?

Back

A transformation that changes the size of a figure but not its shape.

Front

What is the difference between a translation and a dilation?

Back

A translation moves a figure without changing its size or shape, while a dilation changes the size.

Front

If a shape is translated 5 units right and 2 units down, what is the translation rule?

Back

(x, y) → (x + 5, y - 2)

Front

What does the term 'image' refer to in transformations?

Back

The resulting figure after a transformation has been applied.

Front

What is the effect of a scale factor greater than 1 in a dilation?

Back

The figure enlarges.
