# Angles

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

Acute | An angle that measures less than 90° |

Obtuse | An angle that measures more than 90° |

Right | An angle that measures exactly 90° |

Complementary Angles | Two angles whose sum is 90° |

Supplementary Angles | Two angles whose sum is 180° |

Adjacent | Angles that share a vertex and a common side. (Vertex is the corner) |

Vertical Angles | Angles formed by two intersecting lines that are opposite each other, they have equal angle measures. |

Congruent | Angles that are related because they have the same measure |

Parallel Lines | Lines that are the same distance apart at all times and will never cross |

Perpendicular Lines | Lines that intersect at a 90° angle |

Transversal | A line that intersect two other lines |

Alternate Interior Angles | Angles are formed when a transversal passes through two lines. The angles that are formed on opposite sides of the transversal and inside the two lines are __________________. |

Alternate Exterior Angles | Angles are formed when a transversal passes through two lines. The angles that are formed on opposite sides of the transversal and outside the two lines are ______________. |

Corresponding | Angles are formed when a transversal passes through two lines. The angles that are formed in the same position. If the two lines are parallel the _____________ angles are equal. |
