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

acute angle | an angle whose measure is between 0 and 90 |

angle | formed by two rays with the same endpoint |

angle bisector | a ray that divides an angle into two congruent angles |

collinear points | collinear points lie on the same line |

congruent angles | angles that have the same measure |

congruent segments | segments that have the same length |

conjecture | a conclusion reached by using inductive reasoning |

coordinate | a point on a line or plane |

coplanar | points or lines on the same plane |

counterexample | proves a conjecture false |

inductive reasoning | based on a pattern of past events |

line | has no lenght, no width, or thickness. It extends with no end in two directions |

midpoint | the point that divides the segment into two congruent segments |

obtuse angle | an angle whose measure is between 90 and 180 |

oppostie rays | collinear rays with the same endpoint |

parallel lines | two lines are parallel if they lie on the same plane and do not intersect |

perpendicular lines | lines that intersect and form right angles |

plane | contains no thickness, and extends without end in the direction of its lines |

point | a location on a line or plane |

postulate | an accepted statement of fact |

ray | the part of a line consisting of one endpoint and all the points of the line on one side of the endpoint |

right angle | an angle whose measure is 90 |

segment | the part of the line consisting of two end points and all points between them |

skew lines | lines that do not lie on the same plane |

space | the set of all points |
