What would be the new coordinates after rotating (3,6) 270 degree counterclockwise?

1 answer

To rotate the point (3, 6) by 270 degrees counterclockwise around the origin, we can use the rotation formula for a point \((x, y)\):

\[ (x', y') = (y, -x) \]

For a 270-degree counterclockwise rotation, the transformation can also be thought of as equivalent to a 90-degree clockwise rotation.

  1. Start with the original coordinates: \((3, 6)\).
  2. Apply the transformation:

\[ x' = y = 6 \] \[ y' = -x = -3 \]

Thus, the new coordinates after rotating (3, 6) by 270 degrees counterclockwise are \((6, -3)\).
