Analyze Rotations

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)

How many degrees was the figure rotated?

• 90 degrees counterclockwise 

• 180 degrees

• 270 counterclockwise 

• 90 degrees clockwise

Rotate the point (-3,-4) around the origin 180 degrees clockwise. State the image of the point.

• (-4,-3)

• (-4,3)

• (4,-3)

• (3,4)

When a coordinate goes to (-x, -y) it is a 

• 180 degree rotation

• a 90 degree clockwise rotation

• a 90 degree counterclockwise rotation

• A 360 degree rotation

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

• (0, 0)

• (-1, 3)

• (-6, 2)

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)
