angle- side-angle | if two angles and 1 side are congruent in a triangle. |

triangle sum theorem | the sum of the measured of the interior angles if a triangle. |

exterior angle theorem | the measure of an exterior angle is equal to the sum of the measures of the nonadjacent angles. |

hypotenuse leg | the hypotenuse and a leg of a right triangle are congruent to the other leg, then the two triangles are congruent. |

Angle-Angle-Side | if two angles and a non-included side of one triangle are congruent to two angles, then the two triangles are congruent. |

base angles | if two sides of a triangle are congruent, then the two angles opposite them are congruent. |
