If you were to rotate ABCD 180°  about the origin, what would the coordinate of A' be?

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

Triangle A is rotated 270° counterclockwise with the origin as the center of rotation to create a new figure. Which rule describes rotating 270° counterclockwise?

• (x,y)→(y, -x) 
• (x,y)→(x,y)
• (x,y)→(-y,x)
• (x,y)→(-x,-y)

Which answer shows a reflection across the x-axis?

• d
• c
• b
• a

Flipping a figure is a ...

• Rotation

• Reflection

• Dilation

• Translation

A dilation is which of the following: 

• An enlargement
• A reduction
• Either an enlargement or a reduction
• Neither an enlargement or a reduction

Dilate Point B by a scale factor of 3:

• (12,0)
• (12,12)
• (4,3)
• (0,12)

Triangle ABC is dilated using a scale factor of 1/2. What are the new coordinates of point A'?

• (-3, 3)
• (-12, 12)
• (-2, 2)

Simplify the expression: 
c⁴⋅c³=

• ^c12
• c⁴⁺³
• c⁷
