Circumference | c=2PIr or c= PId |

Area of triangle | A=1/2 BH (Base + Height have to meet (unit square,cm square,in square,m square) |

Area of rectangle | A=L times W=B times H (unit square,cm square,in square,ft square,m square) |

Area of square | A=S square=L times W=B times H (units square,cm square,in square,mi square,m square,ft square) |

Area of parallelogram | A=B + H (Base + Height have to meet) unit square,cm square,in square,ft square,m square |

Area of trapezoid | A=1/2 H(B1 +B2) B1 +B2 have to be parallel (B + H have to meet @ 90 degrees |

Volume of cube | Vol.=L times W times H= S3 ( units3,cm3,ft3,in3 cube units) |

Supplementary angles | 2 angles that when added equal 180 degrees (La +Lb=180 degrees) |

Complementary angles | 2 angles that when added equal 90 degrees (sum) |

Vertical angles | 2 angles that are oppiste (share the same measurement) |

Adjacent Angles | 2 angles that are next to each other & share a vertex Lx & Lz are adjcent (Lx + Lz=108 degrees) |

Diamater | A line segment from edge to edge going through the center of the circle (d=2r) |

Radius | A line segment from the edge of the circle to the center of the circle (r=1/2d) |

Area of circle | A=PIr square (units2,mc2,m2,in2,ft2) |

Perimeter of a quadrilateral: P=S1 +S2 +S3 +S4

Perimeter of a rectangle: P=2L + 2H=2B + 2H

Volume of rectangular prism: Vol.=Area times Height=1/2 B times H1 times Height2
