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

similar triangles | triangles in which each pair of corresponding angles are congruent and each pair of corresponding sides are proportional |

scale factor | ratio that describes the relationship between sides of similar figures |

vertical angles | non-adjacent angles formed by opposite rays. these angles are always congruent (their measures are always equal) |

linear pair | adjacent angles formed by the intersection of two lines. these angles are always supplementary (their measures always have a sum of 180 degrees) |

right triangles | triangles in which one angle measures 90 degrees |

acute triangles | triangles in which each angle measures less than 90 degrees |

equilateral triangles | triangles in which all sides have equal measures |

obtuse triangles | triangles in which one angle measures more than 90 degrees |

scalene triangles | triangles in which no sides have equal measures |

isosceles triangles | triangles in which two sides have equal measures |

congruent triangles | triangles in which each pair of corresponding angles are congruent and each pair of corresponding sides are congruent |
