Perform a Dilation

In this dilation, the blue figure is the image and the black figure is the pre-image. This means that an ______________ occurred.

• enlargement

• reduction

• spin

• flip

A __________________ is a transformation that enlarges or reduces the size from pre-image to image based on a scale factor.

• translation

• reflection

• rotation

• dilation

An ________________means that the image is larger than the pre-image.

• reduction

• enlargement

• flip

• spin

When the scale factor is greater than 1 on a dilation, it produces ___________________.

• a reduction

• a pre-image

• a spin

• an enlargement

When dilations have a scale factor of less than 1, it causes a ___________________.

• reduction

• enlargement

• slide

• turn

Which scale factor will cause an enlargement?

• 5

• 0.5

• 5/10

• 0.55

Similar figures are figures that are the SAME shape, but a DIFFERENT size.

Which one of the following transformations will produce a similar figure?

• translation

• dilation

• rotation

• reflection

A dilation with a scale factor of 4 will produce an enlargement.

• true

• false

When trying to find the side lengths of the image or the coordinates of the image in a dilation, what operation do you perform using the scale factor? For example: A (2,1) and the scale factor is 3, A' will be (6,3).

• add

• subtract

• multiply

• divide

A dilation with a scale factor of 1/3 will produce a reduction.

• true

• false
