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

acute angle | an acute is an angle whose mesure is between 0 and 90. |

angle | an angle is formed by two rays with the same endpoint. the rays are side of the angle and comon endpoint is the vertiz of the angle. |

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

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

congruent | anglesangles that have the same mesure |

congruent segments | segments that have the same lenth |

conjectur | a conclusion reach by inductive resoning |

coordinate | |

coplanar | coplaner are figure in the same plase. |

counterexample | a statment that particular example or instence of the statement that makes the statment false. |

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

line | a line is undefined. you can think of a line as a serious of points that extend in two directions with out an ending point. |

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

obtuse angle | an obtuse angle is an angle whosemesure is between 90 and 180 |

oppoosite rays | oppisite rays are colinear rays with the same endpoint the form a line. |

parel lines | two lines are parallel if they lie in the same plane and do not intersect. |

perpendicular lines | lines that intersect and form right angles. |

plane | a plane is undefind. a plane contains maney lines and extends without end in the directions od its lines.p |

point | a point has no size and no location |

postulare | an acceoted statement or fact |

ray | a ray is a point of a line consisting of one endpoint. |

right angle | a right anngle is an angle whose mesure is 90 |

segment | a segment is the point of the line that consist of two points. |

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

space | space is the set of all points |
