Identifying Points on Coordinate Plane After Rotation

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)

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

• (0, 0)

• (-6, -5)

• (-1, 3)

• (-6, 2)

Identify the transformation from B to D.

• 90^o Clockwise Rotation

• 180^o Rotation

• 270^o clockwise Rotation

• 360^o Rotation

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

• 270⁰ clockwise

• 180⁰

• 90⁰ clockwise

Rotate each point 180 degrees:

• (0,-1)

• (0,1)

• (-2,-3)

• (x,y)

• (-5,-7)

• (2,3)

• (5,-7)

• (-5,7)

• (-x,-y)

• (5,7)

Answer explanation

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

(-3, -8)

(-3, -8)

(-8,3)

(3,8)

(-8,3)

(3,8)

To ROTATE 90 degrees clockwise, you follow the rule (x,y) -> (y,-x) Ex: (4,5) becomes (5,-4). Match these below to be 90 degree rotations.

• (3, -10)

• (3,7)

• (7, -3)

• (10,3)

• (4, -9)

• (4,5)

• (5,-4)

• (9,4)

Complete the mapping for a rotation 180 degrees around the origin:

(x, y) --> (​​​​​​ ​ (a)   ,​​​ ​ (b)   )

• x

• -y

• -x

• y
