Rotating A Point

Identify the rule after a 180° CLOCKWISE or COUNTER CLOCKWISE
(x, y) ---> ___________

• ( -x, -y)

• ( -y, x)

• ( -x, y)

• (y, -x)

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)

Rotate the point (7,8) around the origin 90 degrees counterclockwise.
State the image of the point.

• (-7,-8)

• (8,-7)

• (-8,7)

• (8,7)

Rotate the point (-5,8) around the origin 270 degrees counterclockwise. State the image of the point.

• (-8,5)

• (8,-5)

• (8,5)

• (5,-8)

Rotate each point 180 degrees:

• (0,-1)

• (x,y)

• (-x,-y)

• (2,3)

• (-5,-7)

• (5,7)

• (5,-7)

• (0,1)

• (-2,-3)

• (-5,7)

Answer explanation

180 rotation is x,y becomes -x, -y (change the sign of x and y)

Rotate B(4, 1) counterclockwise 90 degrees around the origin. On the graph, click on the correct location of B'.

Complete the mapping for a rotation 90 degrees CLOCKWISE around the origin:

(x, y) --> (​​​​ (a)   ,​ (b)   )

• x

• -y

• -x

• y

Math the correct ROTATION of (x,y)

• (y,- x)

• ROTATE 270 degrees

  COUNTER COUNTERCLOCKWISE

• (-y, x)

• ROTATE 180 degrees

  COUNTER CLOCKWISE

• (-x, -y)

• ROTATE 90 degrees
