What is a scale factor in dilation?

Back

A scale factor is a number that describes how much a figure is enlarged or reduced during a dilation. It 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 greater than 1, what type of transformation occurs?

Back

An enlargement occurs.

Front

If the scale factor is less than 1, what type of transformation occurs?

Back

A reduction occurs.

Front

What does it mean for figures to be congruent?

Back

Congruent figures have the same shape and size.

Front

What is the result of a dilation with a scale factor of 1?

Back

The figure remains unchanged.

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.

Front

What is the scale factor if a point (4, 6) is dilated to (2, 3)?

Back

The scale factor is 1/2.

Front

What are the coordinates of point A(2, 3) after dilation by a scale factor of 3?

Back

A'(6, 9).

Front

True or False: A dilation produces congruent figures.

Back

False. A dilation produces similar figures, not congruent figures.

Front

What is the scale factor if a figure is reduced from a size of 8 to a size of 4?

Back

The scale factor is 1/2.
