### Triangles and the Pythagorean Theorem STUDENT GLOSSARY

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

alternate exterior angles | exterior angles that lie on opposite sides of the transversal, their measures are equal |

alternate interior angles | interior angles that lie on opposite sides of transversal,their measures are equal |

converse | reversed parts of the pythagorean theorm |

corresponding angles | angles that are in the same position on the two lines in relation to the transversal when the lines are parallel their measures are equal |

deductive reasoning | uses facts rules definitions or laws to make conjectures from given situations |

Distance Formula | to find the distance between two points on the coordinate plane |

interior angles | lie inside the lines |

legs | are the sides that form the right angle |

paragraph proof | a paragraph that explains why a statement or conjecture is true |

parallel lines | two lines that are in the same plane |

perpendicular lines | two lines that intersect in a plane and form right angles |
