### Congruence of Triangles

Term | Definition |
---|---|

Congruent Line Segments | line segments that have the same length |

Congruent Angles | angles that are equal in measure |

Corresponding Sides | sides that have the same relative positions in geometric figures |

Corresponding Angles | angles that have the same relative positions in geometric figures |

SSS Congruence Theorem (Side-Side-Side) | if three sides of one triangle are congruent to the corresponding sides of another triangle, then the triangles are congruent |

Included Angle | the angle formed by two sides of a triangle |

SAS Congruence Theorem (Side-Angle-Side) | if two sides and the included angle of one triangle are congruent to the corresponding two sides and included angle of a second triangle, then the triangles are congruent |

Included Side | the line segment between two angles of a triangle |

ASA Congruence Theorem (Angle-Side-Angle) | if two angles and the included side of one triangle are congruent to the corresponding two angles and the included side of another triangle, then the triangles are congruent |

AAS Congruence Theorem (Angle-Angle-Side) | if two angles and a non-included side of one triangle are congruent to the corresponding angles and the corresponding non-included side of a second triangle, then the triangles are congruent |
