A Translation is a movement of a figure without turning it. |

Figure 2. |

Here, the figure has been moved to a new location.

Reflection |

In a Reflection, a figure is “flipped” over a line of symmetry. |

Figure 3. |

Here, the figure has been flipped over a line of symmetry.

Rotation |

In a Rotation, a figure is rotated around a fixed point. |

Figure 4. |
