Dilations and Scale Factor

Front

Dilations

Back

Transformations that change the size of a figure without changing its shape.

Front

How do you find the scale factor in dilations?

Back

Divide the length of the image by the length of the pre-image.

Front

If the scale factor is greater than 1, what happens to the size of the figure in a dilation?

Back

The size of the figure increases.

Front

If the scale factor is between 0 and 1, what happens to the size of the figure in a dilation?

Back

The size of the figure decreases or gets smaller.

Front

Result of applying a dilation with a scale factor of 2 on the origin to the point (3, 4)?

Back

(6, 8)

Front

Result of dilation with scale factor 0.5 on origin to point (-2, -6)?

Back

(-1, -3)

Front

Graph the dilation of the point (2, 3) on the origin with a scale factor of 3.

Back

(6, 9)

Front

Graph the dilation of the point (-1, 5) on the origin with a scale factor of 0.75.

Back

(-0.75, 3.75)

Front

If a figure is dilated on the origin with a scale factor of 2, what happens to the distance between its points and the origin?

Back

The distance between the points and the origin doubles.

Front

If a figure is dilated on the origin with a scale factor of 0.5, what happens to the distance between its points and the origin?

Back

The distance between its points and the origin is halved.
