Front

What is a dilation in geometry?

Back

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

Front

What does a scale factor greater than 1 indicate?

Back

An enlargement of the figure.

Front

What does a scale factor less than 1 indicate?

Back

A reduction of the figure.

Back

Enlargement.

Front

What is the term for a figure that has been reduced through dilation?

Back

Reduction.

Front

If a figure is dilated by a scale factor of 1, what happens to the figure?

Back

The figure remains the same size.

Front

What is the center of dilation?

Back

The fixed point in a dilation from which the figure is enlarged or reduced.

Front

True or False: A scale factor of 2 enlarges a figure by doubling its size.

Back

True.

Front

True or False: A scale factor of 1/3 enlarges a figure.

Back

False.

Front

What happens to the dimensions of a figure when it is dilated by a scale factor of 1/2?

Back

The dimensions are reduced to half their original size.
