Dilations Practice

A non-rigid transformation that moves a point along a line by changing the distance from a fixed point is called a:

A figure that is the RESULT of a transformation is called the:

What do we call a figure BEFORE a transformation is performed?

This tells us how much farther away from, or closer to the center of dilation points will move:

Which one will correctly find scale factor?

• Scale factor = Length of the image / Length of the preimage

• Scale factor = Length of the preimage / Length of the image

CCSS.7.G.A.1

This letter is used to represent scale factor:

• x

• y

• o

• k

When dilating, what mathematical operation is always used with the scale factor?

• addition 
• subtraction 
• multiplication 
• division

CCSS.8.G.A.3

Dilations preserve side length and angle measure.

• True

• False

This is a fixed point that is the starting point for all dilations:

• scale factor

• dilation

• center of dilation

• pre-image

Choose all statements that are true about dilations.

• Dilations cause angle measures to change.

• Dilations cause side lengths to change.

• When k > 1, a dilation results in an enlargement.

• The length of the preimage equals the length of the image times the scale factor.

• Dilations result in a parallel image.
