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

segment addition postulate | if q is between p and r, then PQ + QR = PR |

reflexive property | a=a |

symmetric property | if a =b, then b=a |

transitive property | if a=b, then b=c, then a = c |

addition property | if a = b, then a + c = b + c |

subtraction property | if a = b, then a - c = b - c |

multiplication property | if a = b, then ac = bc |

Division Property | if a = b and c is not equal to 0, then a/c = b/c |

substitution Property | if a = b, then a may be replaced by b in any equation or expression. |

Distributive Property | a(b + c) = ab + ac |

vertical angles | two nonadjacent angles formed by 2 intersecting lines. vertical angles are congruent |

linear pair | adjacent angles whose noncommon sides are opposite rays. sum = 180 degrees |

complementary angles | two angles whose measures have a sum of 90 degrees |

supplementary angles | two angles whose measures have a sum of 180 degrees |

right angle | an angle whose measure is 90 degrees |

acute angle | angles smaller than a right angle |

obtuse angle | angles larger than a right angle |

straight angle | has a measure of 180 degrees |

collinear | points on the same line |

coplanar | points on the same plane |

bisector | intersects at its midpoint |

midpoint | a point M is the midpoint of segment PQ if M is between p and Q and PM = MQ |
