# geo.Lines and angles

### lines/angles postulates and theorems

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

skew lines | lines that do not intersect and are not parallel |

parallel postulate | only 1 line exists that can be drawn through a point and parallel to a specific line |

perpendicular postulate | only 1 line exists that can be drawn through a point and perpendicular to a specific line |

transversal | any line that intersects 2 or more lines |

corresponding angles postualte | angels in the same positions- correspond to each other are congruent |

alternate interior angles theorem | if 2 parallel lines are cut by a transversal, then the pairs of alternate interior angles are congruent |

consecutive interior angles theorem | if 2 parallel lines are cur by a transversal then the pairs of consecutive interior angles are supplementary |

alternate exterior angles | if 2 lines are cut by a transversal then the pairs if alternate exterior angles are congruent |

perpendicular transversal | if a transversal is perpendicular to 1 out of 2 parallel lines, then it is perpendicular to the other |

corresponding angles converse | if 2 lines are cut by a transversal so that corresponding anglews are congruent, then the lines are parallel |

alternate interior angles converse | if 2 lines are cut by a transversal so that alternate interior angles are congruent, then the lines are parallel |

consecutive interior angles converse | if a transversal cuts 2 lines so that the consecutive interior angles are supplementary, then the lines are parallel |

alternate exterior angles converse | if a transversal cuts 2 lines so that the alternate exterior angles are congruent then the lines are parallel |
