Rotations: Find the Coordinates
| Question | Answer |
|---|---|
| Rotation of 90 degrees clockwise about the origin | (x,y) -> (y,-x) |
| Rotation of 180 degrees clockwise about the origin | (x,y) -> (-x,-y) |
| Rotation of 270 degrees clockwise about the origin | (x,y) -> (-y,x) |
| Rotations of 90 degrees counterclockwise about the origin | (x,y) -> (-y,x) |
| Rotations of 180 degrees counterclockwise about the origin | (x,y) -> (-x,-y) |
| Rotations of 270 degrees counterclockwise about the origin | (y,-x) -> (y,-x) |
| (x,y) -> (y,-x) | 90 degrees clockwise and/or 270 degrees counterclockwise |
| (x,y) -> (-x,-y) | 180 degrees clockwise and/or counterclockwise |
| (x,y)->(-y, x) | 270 degrees clockwise and/or 90 degrees counterclockwise |
| (3,4) -> (-4,3) | 90 degrees counterclockwise and/or 270 degrees clockwise |
| (3,4) -> (4,-3) | 90 degrees clockwise and/or 270 degrees counterclockwise |
| (3,4) -> (-3,-4) | 180 degrees counterclockwise and/or clockwise |
