Straight angle | An angle created by two opposite light ray that actions 180°. |

Acute angle | An angle the measures greater than 0° and less 보다 90°. |

Right angle | An angle that procedures 90°. |

Interior of an angle | The collection of all points in between the sides of an angle. |

Obtuse angle | An angle the measures higher than 90° and less than 180°. |

Exterior of an angle | The set of all points external an angle. |

Adjacent angles | Two angles in the same aircraft with a usual vertex and also a typical side, but no usual interior points. |

Complementary angles | Two angle whose measures have actually a sum of 90°. |

Supplementary angles | Two angles whose measures have a sum of 180°. |

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

Linear pair | A pair of surrounding angles whose noncommon sides space opposite rays. |
