The new figure that results from the transformation of a figure in a plane. | image |

The original figure in the transformation of a figure in a plave. | preimage |

The aperation that maps, or moves, a preimage onto an image. Three basics are reflections, rotations and translations. | transformation |

A transformation that preserves lengths. | isometry |

A type of transformation that uses a line that acts like a mirror. | reflection |

Tye of transformation that uses aline that acts like a mirror. | line of reflection |

A line that a figure in the plane has if the figure can be mapped onto itself by reflection in the line. | line of symmetry |

A type of transformation in which a figure is turned about a fixed joint. | rotation |

A fixed point in which a figure is turned around. | center of rotation |

The angle formed when rays are drawn from the center of rotation to a point and its inage. | angle of rotation |

A figure in the plane hae rotational symmetry if the figure can be mapped onto itself by a rotation of 180 degrees of less. | rotational symmetry |

A quantity that has both direction and magnitude, and is represented by an arrow drawn between two points. | vector |

The starting point of a vector. | initial point of a vector |

The ending point of a vector. | terminal point of a vector |

The form of a vector that combines the horizontal and vertical components of the vector. | component form |

The result when two or more transformations are combined to produce a single transformation. | composition of transformation |

A pattern that extends to the left and right in such a way that the pattern can be mapped onto itself by a horizontal translation. | frieze pattern or border pattern |
