A rotation maps point A to A’. On a coordinate plane, point A prime is (negative 3, 4) and A is (3, negative 4). Which statement describes the rotation? 270° counterclockwise rotation 90° clockwise rotation 180° rotation 90° counterclockwise rotation

Answer:

(C)180° rotation

Step-by-step explanation:

For rotations about the origin, these are some basic rules

  • 90°clockwise rotation: (x,y)=(y,-x)
  • 90°counterclockwise rotation: (x,y)=(-y,x)
  • 180° rotation: (x,y)=(-x,-y)
  • 270°counterclockwise rotation: (x,y)=(y,-x)

Given point A(-3,4), x=-3, y=4

Point A'=(3,-4)=(-x,-y)

Therefore, the rotation that maps A to A' is 180 degrees rotation.

The correct option is C.

180 rotation is my best guess
