# Parallelograms

### Geometry definitions needed to solve proofs about Parallelograms

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

parallelgram | If a quadrilateral with both pairs of opposite sides // then parallelograme |

trapezoid | If a quadrilateral with exactly one side pair of opposite sides // then trapezoid |

Distance Between // Lines | Is the length of the prependicular segment from a point on line1 and line 2. |

If 2 lines are // | then they are equdistant every where |

If a quadrilateral is a parallelgram then | both pairs of opposite sides are // |

If a quad. is a para llelagram then | both pairs of opposite side are conguent |

If a quad. is a parallelgram then | both pairs of opposite angles are congruent. |

If quad. is a parallelgram then | consecutive angles are supplementary |

If a quad. is a parallelgram then | diagonals bisect each other |

If both pairs of opposite sides of a quad are // | then parallelogram |

If both pairs of opposite sides of a quad. are congruent | then parallelogram |

If one pair of opposite sides of a quad are both congruent and // | then parallelogram |

If both pairs of opposite angles of a quad. are congrunt | then parallelogram |

If the diagonals of quad. bisects each other | then paralleogram |

If 3 or more // lines intecpt congrunt segments on one transversal then | intersect congrunt on every transversal. |
