translation | | a mirror image or result of a reflection |

map | | Repeats itself along a straight line |

composition | | when line of reflection is perpendicular bisector of segment BB' |

tiling | | a transformation does this to a figure onto its image |

linesymmetry | | dilation by a factor less than 1 |

preimage | | transformation that uses circular motion |

isometry | | when an image is congruent to its preimage |

reflection | | when the image is enlarged or reduced |

primenotation | | when a half turn maps a figure onto itself |

scalefactor | | change in position, size or shape of a figure |

image | | a tessellation |

symmetry | | an isometry that maps a figure onto itself |

dilation | | original figure in a transformation |

transformation | | the result of a transformation |

rotation | | a repeating pattern of figures that completely covers a plane without overlap or gaps |

friezepattern | | more than one transformation at a time |

reduction | | composition of translation followed by reflection |

glidereflection | | used to identify image points |

pointsymmetry | | describes size change from preimage to image |

tessellation | | moves all points of a figure the same distance and direction |
