You are watching: Two angles whose sides are opposite rays are called

AB | |

The allude that divides a segment right into two congruent segments. | |

Acute angle | An angle that measures greater than 0 yet less than 90 degrees. |

Vertical angles | Two angle whose sides kind two bag of the contrary rays. |

Supplementary angles | Two angles whose sum is 180 degrees. |

Linear pair postulate | If two angles kind a linear pair, then they room supplementary and their amount is 180 degrees. |

Perpendicular lines | Two currently that crossing to form a appropriate angle. |

Segment bisector | Segment, ray, line, or plane that intersects a segment at its midpoint. |

Congruent angles | Two angles that have the exact same measure. |

Complementary angles | Two angles whose amount is 90 degrees. |

Adjacent angles | Two angles that re-superstructure a vertex and also common side yet have no inner points in common. |

Linear pair | Two adjacent angles whose noncommon sides room opposite rays. |

Obtuse angle | An angle the measures an ext than 90 degrees and also less 보다 180. |

Right angle | An gngle that measures 90 degrees. |

Angle bisector | A beam that divides one angle right into two congruent angles. |

Theorem | A statement that need to be confirmed to it is in true. |

Postulate | A statement the is accepted as true without proof. |

Collinear | Points, present or segments that room on the very same line. |

Coplanar | Points, lines , or planes in the very same plane |

Converse | q implies p |

Inverse | Not p implies not q |

Contrapositive | Not q suggests not p |

Congruent Complements Theroem | If two angles space complementary come the exact same angle, climate they are congruent. |

Congruent additional Theorem | If 2 angles room supplementary come the same angle, then they space congruent. See more: How Many Core Electrons Are In A Chlorine Atom? ? How Many Core Electrons Does A Chlorine Atom Have |

Vertical angles Theroem | If two angles space vertical angles, climate they are congruent. |
