# Chap 10 Quiz Geometr

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

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

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

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

chord | a segment whose endpoints are on a circle |

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

common internal tangent | goes between the circles |

common external tangent | goes on the same side of the outside of the circles |

point of tangency | the point of which a tangent touches a circle |

circle with right triangle with radius as one side | pythagorean theorem |

tangents that meet at one point | set equal |

semicircle | =180* |

minor arc | <180 |

major arc | >180 |

an inscribed angle is always - the measure of the intercepted arc | 1/2 |

inscribed angles | if two inscribed angles are intercepting the same arc, then they are congruent |

inscribed triangles | if one side of the triangle is the diameter, it is a right triangle |

chords | 1. if one chord is the perpendicular bisector of another chord, then it is a diameter 2. if a diameter is perpendicular to another chord, then it bisects the chord |

equidistant chords | in the same circle or congruent circlestwo chords are congruent if and only if they are equidistant to the center of the circle |
