Dilations and Scale Factor

Front

What happens to a figure when the scale factor is less than 1?

Back

The figure undergoes a reduction.

Front

What is the scale factor if the dilation results in a smaller figure?

Back

The scale factor is less than 1.

Front

If two polygons are similar, what can be said about their corresponding angles?

Back

The corresponding angles are congruent.

Front

What is the scale factor from a smaller shape to a larger shape if the scale factor is 2?

Back

The larger shape is twice the size of the smaller shape.

Front

If the scale factor to map A'B'C' onto ABC is 1/4, what is the scale factor to map ABC back onto A'B'C'?

Back

The scale factor is 4.

Front

What is a dilation in geometry?

Back

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

Front

What is the scale factor in a dilation?

Back

The scale factor is the ratio of the length of a side of the image to the length of the corresponding side of the original figure.

Front

If the scale factor is 5/2, is the dilation an enlargement or a reduction?

Back

The dilation is an enlargement.

Front

What does it mean if a scale factor is equal to 1?

Back

The figure remains the same size; it is neither enlarged nor reduced.

Front

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

Back

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