• Translation

• Reflection

Does the image show a Dilation? If yes, did the image enlarge, reduce or none of the above?

• Yes, enlarge

• Yes, reduce

• No

Dilation is a type of ...

• rigid transformation

• non-rigid transformation

a transformation that ​changes the size (enlargement or reduction) of a figure is called a ​ ​ ​ (a)  

• dilation

• rotation

• reflection

• translation

CCSS.8.G.A.3

If the scale factor is greater than 1, the dilation is (a)  

• an enlargement

• a rotation

• a translation

• a reduction

Which of the following is NOT a rigid transformation?

• reflection

• dilation

• rotation

• translation

CCSS.HSG.CO.B.6

Match the following

• Rigid Transformations

• Dilation

• Center of origin

• The factor by which every length in

  the pre-image is increased or decreased when

  you make a scaled copy

• Non-Rigid Transformations

• Translation, Reflection, Rotation

• Scale Factor

• The process of resizing an object by a certain scale factor

• Dilation

• The origin is often used as the center of dilation. If you are dilating a figure centered at the origin, you can multiply the coordinates of the points in the preimage by the scale factor to determine the points in the image
