---|---|

set of all points in a plane that are equidistant from a given point. | circle |

of a circle, given point | center |

a segment whose endpoints are the center and any point of the circle | radius |

a segment whose endpoints are on a circle | chord |

a chord that contains the center of a circle | diameter |

a line that intersects a circle in two points | secant |

a line in the plane of a circle that intersects the circle in exactly one point | tangent |

on a circle is an angle whose vertex is the center of the circle | central circle |

ACB, endpoints are AB | minor arc |

point C doesnt lie on AB | major arc |

is an arc with endpoints that are the endpoints of a diameter | semicircle |

is the measure of its central angle | measure of a minor arc |

is the difference between 360 degrees and the measure of the related minor arc | measure of a major arc |

two circles with the same radius | congruent circles |

two arcs with the same measure are . they are arcs of the same circle or congruent circles | congruent arcs |

an angle whose vertex is on a circle and whose sides contain chords of the circle | inscribed angle |

the arc that lies in the interior of an inscribed angle and has endpoints on the angle | inscribed arc |

when two chords intersect in the interior of a circle each chord is divided into two segments | segments of the chord |

a segment that contains a chord of a circle and has exactly one endpoint outside the circle | secant segment |

the part of a secant segment that is outside the circle | external segment |
