How do you translate a point? | Add |

How do you reflect a point over the x-axis? | Same x coordinates, opposite y coordinates |

How do you reflect a point over the y-axis? | Same y coordinates, opposite x coordinates |

How do you rotate a point (x,y) 90 degrees counterclockwise? | Write the opposite original y coordinate as you new x coordinate, then copy the original x coordinate as your new y coordinate. (-y, x) |

How do you rotate a point (x, y) 180 degrees? | Write the opposite of all coordinates. (-x, -y) |
