Dilations and Scale Factor A

Front

What is a dilation?

Back

A dilation is a transformation that alters the size of a figure, either enlarging or reducing it, while maintaining its shape.

Front

What does a scale factor greater than 1 indicate?

Back

A scale factor greater than 1 indicates an enlargement of the figure.

Front

What does a scale factor less than 1 indicate?

Back

A scale factor less than 1 indicates a reduction of the figure.

Front

What is the scale factor if the original figure is reduced to half its size?

Back

The scale factor is 1/2.

Front

If a figure is dilated with a scale factor of -2, what happens to its orientation?

Back

The figure is enlarged by a factor of 2 and reflected across the origin.

Front

What is the effect of a scale factor of 1 on a figure?

Back

A scale factor of 1 means the figure remains the same size; it is unchanged.

Front

How do you determine if a dilation is an enlargement or a reduction?

Back

If the scale factor is greater than 1, it is an enlargement; if it is less than 1, it is a reduction.

Front

What is the scale factor if a figure is enlarged to twice its original size?

Back

The scale factor is 2.

Front

Can a dilation be both an enlargement and a reduction?

Back

No, a dilation can only be one or the other, depending on the scale factor.

Front

What happens to the dimensions of a figure when it is dilated by a scale factor of 3?

Back

All dimensions of the figure are multiplied by 3, resulting in an enlargement.
