Term | Definition |
---|---|

Point | Represented by a dot, has no dimension. |

Plane | Two dimensions, any three points make a____. i.e.a floor or wall that extends forever. |

Angle Bisector | A ray that divides an angle into two congruent angles. |

Supplementary Angles | Two angles with a sum of 180 degrees. |

Complimentary Angles | Two angles with a sum of 90 degrees. |

Opposite Rays | 2 rays that extend in opposite directions. |

Vertical Angles | "Kissing fish." Angles that are across from each other are congruent. |

Line | One dimension, extends forever in both directions. Any two points make a ____. |

Angle | Two different rays (sides) with the same endpoint (vertex). |

Collinear Points | Points that lie on the same line. |

Coplanar Points | Points that lie on the same plane. |

Acute Angle | An angle that is less than 90 degrees. |

Right Angle | An angle that is 90 degrees. |

Obtuse Angle | An angle that is greater than 90 degrees and less than 180 degrees. |

Straight Angle | An angle that is 180 degrees. |

Line Segment | Contains two endpoints and all points in between. Represented by endpoints. |

Midpoint | Divides a line segment into two congruent line segments. |

Linear Pair | Two adjacent angles that make 180 degrees (sides are opposite rays). |

Congruent | Equal |

Segment Bisector | A point, ray, line, line segment, or plane that intersects the segment at its midpoint. |
