complementary | Two or more angles whose measures add up to 90 degrees |

compound | Interest earned or paid on the principal and previously earned or paid interest |

cone | A 3-D figure with one vertex and one circular base |

congruent | Having the same size and shape |

correlation | The description of the relationship between two data sets |

corresponding | A pair of angles that lie on the same side of the transversal and on the same sides of the other two parallel lines |

cylinder | A 3-D figure with two parallel, congruent circular bases connected by a curved lateral surface |

degree | The unit of measure for angles and temperature |
