Dilations and Scale Factor

Front

What is the definition of a scale factor in dilations?

Back

The scale factor is a number that describes how much a figure is enlarged or reduced during a dilation.

Front

If the scale factor is 1/2, what happens to the size of the figure?

Back

The figure is reduced to half its original size.

Front

How do you express a dilation with a scale factor of 3 in algebraic notation?

Back

(x, y) goes to (3x, 3y).

Front

What is the result of a dilation on a figure?

Back

A dilation produces a similar figure.

Front

What are the two types of dilations?

Back

Enlargement and reduction.

Front

If a figure is dilated with a scale factor greater than 1, what type of dilation is it?

Back

It is an enlargement.

Front

If a figure is dilated with a scale factor less than 1, what type of dilation is it?

Back

It is a reduction.

Front

What does it mean for two figures to be similar?

Back

Two figures are similar if they have the same shape but may differ in size.

Front

Can a dilation change the shape of a figure?

Back

No, a dilation does not change the shape, only the size.

Front

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

Back

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