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

acute angles | an angle that is less than 90 degress |

congruent angles | angles that have the same measurement |

coplanar | points and line in the same plane |

midpoint | the middle of a line |

perpendicular lines | intersect to form right angles. |

ray | is a part of a line that consist of an intial point and all points on the line that lie on one side of the intial point |

space | is the boundless three dimensional set of all points. |

angle | two rays that are connected at their endpoints. |

congruent segments | two segments with the same length. |

counterexample | an example or fact that is inconsistent with a hypothesis and may be used in argument against it |

obtuse angle | angle thats more than 90 degrees |

plane | a plat surface that has no thickness. it extends in all directions |

right angle | an angle that is exactly 90 degrees |

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

conjecture | is a conclusion reached by using inductive reasoning |

inductive reasoning | a type of reasoning that reaches conclusions based on a pattern of specific examples or past events. |

opposite rays | are collinear rays with the same endpoint. they form a line |

point | has no length, width, or thickness, but has a position. LOCATION |

segment | the part of a line consisting pf two points, called endpoints, and all points between them |

collinear points | points that lie on the same line. |

coordinate | Any of a set of two or more numbers used to determine the position of a point, line, curve, or plane in a space of a given dimension with respect to a system of lines or other fixed references. |

line | has length, but no width or thickness. it extends without end in two directions |

parallel lines | are coplanar lines that do not intersect |

postulate | a statement accepted to be true without proof |

skew lines | are noncoplanor lines, not parallel, not intersect |
