dialations

Is this transformation a dilation?

• No, scale factor isn't the same.
• Yes, scale factor is the same

In a dilation what mathematical operation is used with the scale factor?

• addition 
• subtraction 
• multiplication 
• division 

The red triangle has been dilated by a scale factor of 1/4, which triangle is it's image? 

• green triangle 
• red triangle 
• black triangle
• none of these 

Choose the correct scale factor:

• 2
• 3
• 1/3
• 1/2

A scale factor of less than one means

• that the image will be larger than the pre-image.
• That the image will be the same as the preimage.
• That you need to subtract that amount off of each side.
• That the image will be a reduction of the preimage.

A scale factor of 1/2 reduces a figure.

• True
• False

A dilation creates a similar figure.

• True
• False

Dilate the figure by a scale factor of 3 with the origin as the center of dilation. What are the coordinates of the image?
A(3,3) B(6,6) C(9,3)

• A'(9,9) B'(18,18) C'(27,9)
• A'(6,6) B'(9,9) C'(12,6)
• A'(0,0) B'(3,3) C'(6,0)
• A'(1,1) B'(2,2) C'(3,1)

The point (8, 12) was dilated to become point (2, 3). What was the scale factor?

• ½
• ¼
• 4
• 2

Dilate Point B by a scale factor of 1/2

• (1.5,-4)
• (-1.5,1)
• (-1,-1.5)
