---|---|

is a closed geometric figure with sides formed by three or more coplaner segments that intersects two other segments, one at each endpoint | polygons |

are polygon thay are formed inside the polygon | interior angle |

3 sided | triangle |

4 sided polygon | quadrilateral |

5 sided polygon | pentagon |

6 sided polygon | hexagon |

7 sided polygon | heptagon |

8 sidd polygon | octagon |

9 sided polygon | nonagon |

10 sided polygon | decagon |

12 sided polygon | dodcagon |

all the angles added up t equal 180 degrees | sum interior angle |

is a polygon that is both equiangular with all angles congruet, and equilateral with all sides congruent | regular polygon |

thw sum of the measures if the interior angles of a convex n-gon is (n-2)180 | interior angle of a regular polygon |

is a polygon that is caved in | convex |

is a polygon that has not caved in | concave |

all of the interior angle are congruent | equaianqular polygon |

all of its sides are congruent | equilateral polygon |

is formed by extending the sides of the polygn | exterior angle |

all the exterior angles on the outside of the polygon add up to 360 | sum exterior angle |

360\n | exterior angle of a regual polygon |

is a polygon that joins two nonconsecutive vertices | diagonal |

is a point from each point is the same | equidistant |

is a segment from a vertext of the triangle to the midpoint of the opposite side of the triangle | median |

a segment, ray, line or plane that is perpendicular to the segment at its midpoint | perpendicular bisector |

is a bisector of an angle of the triangle | angle bisector |

the point of intersection of the line | point of concurrenccy |

the point of concurrency of the angle bisector | incenter |

the point of concurrency of the altitudes of a triangle | orthacenter |
