8th grade rotations and dilations

What is a transformation that turns a figure about a fixed point for a given angle?

• Point of Rotation 
• Vertex 
• Rotations
• Image 

A dilation produces a similar figure

• True

• False

If the scale factor is greater than 1, the dilation is...

• an enlargement
• a rotation
• a translation
• a reduction

If the scale factor is less than 1, the dilation is...

• an enlargement
• a translation
• a rotation
• a reduction

If you were to rotate ABCD 90° counterclockwise about the origin, what would the coordinate of A' be?

• (-5, 5)
• (-3, 5)
• (-5, 3)
• (-3, 3)

Identify the transformation from A to D.

• 90^o Clockwise Rotation
• 180^o Rotation
• 270^o  clockwise Rotation
• 360^o Rotation

Choose the correct scale factor:

• 2
• 3
• 1/3
• 1/2

Dilate Point C by a scale factor of 3:

• (12,0)
