Alternate Exterior Angles | Nonadjacent exterior angles that lie on opposite sides of the transversal. |

Alternate Interior Angles | Nonadjacent interior angles that lie on opposite sides of the transversal. |

Consecutive Interior Angles | Interior angles that lie on the same side of the transversal. |

Corresponding Angles | Lie on the same side of the transversal. |

Equidistant | The distance between two lines measured along a perpendicular line is always the same. |

Parallel Lines | Coplanar lines that do not intersect. |

Parallel Planes | Planes that do not intersect. |

Point-Slope Formula | An equation of the form y-y=m(x-x) where (x,y) are the coordinates of any point on the line and m is the slope of the line. |

Rate of Change | Describes how a quantity is changing over time. |

Skew Lines | Lines that do not intersect and are not coplanar. |

Slope | For a line containing two points (x1,y1) and (x2,y2) the number M has given by the formula m=y2-y1/x2-x1 |

Slope-Intercept Form | A linear equation of the form y=mx+b. The graph of such an equation has slope m and y-intercept b. |

Transversal | A line that intersects two or more coplanar lines at two different points |
