a line segment whose endpoints lie on the circle | chord |

an angle whose measure is 90 | right angle |

an angle whose measure is between 90 and 180 | obtuse |

a triangle with one obtuse angle | obtuse triangle |

a triangle with no congruent sides | scalene triangle |

two lines that intersect to form a 90 degree angle | perpendicular lines |

a triangle with two congruent sides | isosceles triangle |

a ray that divides an angle into two congruent angles | an angle bisector |

corresponding parts of congruent triangles are congruent | CPCTC |

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

two angles whose measures add to 90 | complementary angles |

In a triangle, a line drawn from the vertex of an angle to the midpoint of the opposite side | median |

an equilateral rectangle | square |

a line segment whose endpoints lie on the circle and the segment passes through the center of the circle | diameter |

a triangle with all angles congruent | equiangular triangle |

equals the sum of the remote interior angles | exterior angle |

one endpoint at a vertex of a triangle and the other on the line that contains the side opposite the vertex, so that the segment is perpendicular to this side | altitude |

an equilateral parallelogram | rhombus |

the point that divides a segment into two congruent segments | midpoint |

an angle whose measure is between 0 and 90 | acute angle |

a triangle with all sides congruent | equilateral triangle |

coplanar lines that do not intersect | parallel lines |

a parallelogram with four congruent angles | rectangle |

non-coplanar lines that do not intersect | skew lines |

two angles whose sum equals 180 degrees | supplementary angles |

two angles that share a common vertes but not a common side | vertical angles |

two angles that share a common side and whose outer sides form a straight line | linear pair |

the process of observing data, looking for patterns and making generalizations | inductive reasoning |
