Rotations on Graph

How many degrees was the figure rotated?

• 90 degrees counterclockwise 

• 180 degrees

• 90 degrees clockwise

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 type of rotation does this represent (from red to blue)?

• 270⁰ clockwise

• 360⁰

• 90⁰ counterclockwise

• 180⁰

Identify the transformation from A to D.

• 90^o Clockwise Rotation

• 180^o Rotation

• 270^o  clockwise Rotation

• 360^o Rotation

Transformations are when you

• turn, flip, or slide a shape on a graph

• erase a shape on a graph

When the point (7, 8) rotates around the origin 90 degrees counterclockwise, the image will be in Quadrant 2. State the image of the point.

• (-7,-8)

• (8,-7)

• (-8,7)

• (8,7)

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

• ( y , x )

• ( -y , x )

• ( -x , y )

• ( -x , -y )

If (3,2)→(-3,-2) represents a counterclockwise rotation of the point on a coordinate plane, how many degrees is the rotation?

• 90

• 180

If (4,-2) → (-2, -4) represents a counterclockwise rotation of the point on a coordinate plane, how many degrees is the rotation?

• 90

• 180
