What is a tangent segment? |
A segment that is tangent to a circle at an endpoint |

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

What is an external segment? |
Part of the secant segment outside of the circle |

What is the segments of secants theorem? |
If 2 secant segments share the same endpoint outside of a circle then the product of the lengths of one secant segment and it's external segment equals the products of the lengths of the other secant segment and it's external segment |

What is the segments of secants and tangents theorum? |
If a secant and a tangent segment share an endpoint outside a circle, the product of the lengths of the secant segment and it's external segment equals the square of the length of the tangent segment |

What is the segments of chords theorum? |
If 2 chords intersect in the interior of a circle, then the product of the lengths of the segments of one chord is equal to to the product of the lengths of the other chord |
