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

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

right angle | an angle whose measure is 90 |

obtuse angle | an angle whose measure is 90-180 |

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

skew lines | Skew or skew lines lie on different planes. They are neither parallel nor intersecting. Mathematics In geometry, straight lines in a space referred to as skew if they ... |

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

collinear points | points that lie on the same line |

coplanar | being or operating in the same plane |

opposite rays | are collinear rays with the same end point. They form a line. |

perpendicular bisector | The perpendicular bisector of a segment is a line, segment, or ray that is perpendicular to the segment at its midpoint. |

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

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

line | a series of points that extend in two directions |

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

midsegment | line in the center of a figure |

complementary angles | two angles that are complementary angles if the sum of their angles measures is 90 |

supplemenary angles | two angles are supplementary if the sum of their measures is 180 |

adjacent angles | two coplanar angles that have a common side and a common vertex but no common interior points. |

multiplication property of equality | if a=b, then a.c = b . c |

addition property of equality | if a = b than a + c = b + c |

subtraction property of equality | if a = b then a - c = b - c |

division property of equality | if a = b then c does not equal 0 then a/c + b/c |
