Front

What is a dilation?

Back

A transformation that produces a similar figure by enlarging or reducing it based on a scale factor.

Front

What does a dilation produce?

Back

A similar figure.

Front

What mathematical operation is used with the scale factor in a dilation?

Back

Multiplication.

Front

What is the algebraic representation for a dilation with a scale factor of 3?

Back

(x, y) → (3x, 3y).

Front

What happens when the scale factor of a dilation is less than one?

Back

The dilation is a reduction.

Front

What is the figure called after a transformation has occurred?

Back

Image.

Front

What is the figure called before a transformation has occurred?

Back

Pre-image.

Front

If a dilation has a scale factor greater than one, what type of transformation is it?

Back

An enlargement.

Front

If a dilation has a scale factor of 1, what happens to the figure?

Back

The figure remains the same size.

Front

What is the scale factor in a dilation?

Back

A number that describes how much the figure is enlarged or reduced.
