Dilation

Front

What is the definition of Dilation in geometry?

Back

Dilation means to enlarge or reduce a figure based on a scale factor.

Front

What is a scale factor in the context of dilation?

Back

A scale factor is a number that scales, or multiplies, the dimensions of a figure during dilation.

Front

What does a scale factor of less than one indicate?

Back

A scale factor of less than one indicates that the image will be a reduction of the pre-image.

Front

What does a scale factor of greater than one indicate?

Back

A scale factor of greater than one indicates that the image will be an enlargement of the pre-image.

Front

What is the term for the figure before a transformation occurs?

Back

The term is 'pre-image'.

Front

If a point B is dilated by a scale factor of 3, what is the new position of point B if it was originally at (0, 4)?

Back

The new position of point B would be (0, 12).

Front

How do you calculate the coordinates of a dilated point?

Back

To calculate the coordinates of a dilated point, multiply the original coordinates by the scale factor.

Front

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

Back

A scale factor of 1 means the figure remains unchanged.

Front

What is the relationship between the pre-image and the image in dilation?

Back

The image is the result of applying the dilation transformation to the pre-image.

Front

Can dilation change the shape of a figure?

Back

No, dilation does not change the shape of a figure; it only changes its size.
