Standard form of a parabola? | y = a ( x - h ) ^ 2 + k |

What is a circle? | A set of all points on a plane that are equidistant from a given point called the center |

Standard form of a circle? | ( x - h ) ^ 2 + ( y - k ) ^ 2 = r ^ 2 |

What is an ellipse? | Set of all points on a plain such that the sum of the distances from two fixed points is constant |

Standard form of a vertical ellipse? | ( x - h ) ^ 2 / b ^ 2 + ( y - k) ^ 2 / a ^ 2 |

Standard form of a horizontal ellipse? | ( x - h ) ^ 2 / a ^ 2 + ( y - k) ^ 2 / b ^ 2 |

What is a hyperbola? | Set of all points on a plane such that the absolute value of the difference of the distances from the foci is constant |
