### vocab for 1-1

Question | Answer |
---|---|

adjacent angles | two angles that lie in the same plane and have a common vertex and a common side but no common interior points |

linear pair | a pair of adjacent angles with noncommon sides that are opposite rays (form a line) |

vertical angles | two nonadjacent angles formed by two intersecting lines. (congruent) |

complementary angles | two angles with measure that have a sum of ninety |

supplementary angles | two angles with measures that have a sum of 180 the angles in a linear pair are supplementary |

undefined terms | terms that can only be explained by the use of examples or descriptions exactly 1=one and only one |

point | a location it has nieether shape or size named by capital letter (point A) |

line | made up of points has no thickness or width exactly one line through many points named by: letters representing two points on the line or a lower case script letter (line m) |

plane | a flat surface made up of points that extend infinately in all directions. exactly one plane through any three points not on the same line. named by: a capital script letter or by the letters naming three points that are not all on 1 line |

collinear | points that lie on the same line |

noncollinear | points that do not lie on the same line (can use these points to name a plane) |

coplane | points that lie on the same plane |

noncoplanar | points that do not lie in the same plane |

dimension | point has no dimension |

intersection | two or more geometric figures is the set of points they have in common 2 lines intersect at a point |

definitions/defined terms | these are explained by undefined terms or other defined terms |

space | boundless three dimensional set of all points. contains lines and planes |
