Rotation

A transformation that “turns” a figure about a fixed point at a given angle and a given direction.

• reflection
• translation
• rotation
• dilation

What is this picture an example of? 

• An angle
• A cat vertex 
• Rotation 
• Dilation

The name of the figure before the rotation is... 

• Congruent 
• Preimage 
• Image 
• The Before

The image A'B'C' is a rotation of ABC.

• True
• False

Identify the transformation from A to D.

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

Triangle C is rotated 180° clockwise with the origin as the center of rotation to create a new figure. Which triangle shows the new location?

• A
• B
• C
• D

What is the angle of the clockwise rotation?

• 90°

• 180°

• 270°

A counterclockwise rotation of 90° is equivalent to how many degrees of rotation clockwise?

• 90°

• 180°

• 270°

• 360°

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)

When you rotate 180 degrees the ( x , y ) becomes ?

• ( y , x )

• ( -y , x )

• ( -x , y )

• ( -x , -y )
