Angle Addition Postulate |
BC is between <ABD if and only if <ABC +<CBD = <ABD. |

Angle Bisector |
BC is an angle bisector of <ABD if and only if <ABC congruent <CBD |

Definition of Right angle |
It is a right angle if and only if measure of the angle = 90^{0} |

Definition of Supplementary |
Two angles are supplementary if and only if their sum is 180^{0} |

Definition of complementary |
Two angles are complementary if and only if their sum is 90^{0} |

Vertical Angles |
If two angles are vertical then they are congruent |

Linear Pairs |
If two angles are linear pairs then they equal 180^{0} |

Add. Prop. of Equ |
If <A = <B, then <A + <C = <A + <C |

Sub. Prop. of Equ. |
If <A = <B, then <A - <C = <B - <C |

Multi. Prop pf Equ. |
If <A = <B, then <C (<A) = <C (<B) |

Divide Prop of Equ. |
If <A = <B, then <A / <C = <B / <C |

Substitution: |
If RA = RB, then RA can replace RB |

Reflexive: |
RA = RA |

Symmetric |
RA = RB, then RB = RA |

Transitive |
If RA = RB and RB = RC, then RA = RC |

Right angle @ |
All right angles are congruent
to each other |

Congruent Supplements |
If two angles are supplementary to same or congruent angles then they are congruent. |

Congurent Complements |
If two angles are complementary to same or congruent angles then they are congruent. |

Definition of Congruency: |
If <1 is congruent to <2, then m<1 = m<2 |
