  1. ROTATIONS IN THE COORDINATE PLANE

  2. 90⁰ Rotation To rotate a point 90⁰ counterclockwise about the origin, multiply the y-coordinate by -1 and then interchange the x- and y-coordinates. Symbols (x,y)(-y,x) To rotate a point 90⁰ clockwise about the origin, multiply the x-coordinate by -1 and then interchange the x- and y-coordinates. Symbols (x,y) (y,-x) ROTATIONS IN THE COORDINATE PLAN

  3. 180⁰ Rotation To rotate a point 180⁰ counterclockwise or clockwise about the origin, multiply the x- and y- coordinates by -1. Symbol (x,y)(-x,-y) ROTATIONS
