# Geometry - BBMS 2012

### Twenty-four geometry terms

Question | Answer |
---|---|

line | a straight path goes on and on in both directions |

line segment | Two endpoints and a straight path that lies between them |

ray | A part of a line that goes on and on in one direction |

point | A location in space named by an ordered pair |

plane | A flat surface that extends on and on in all directions |

vertices | Vertex is the point where two rays intersect to form an angle. Vertices are more than one vertex. |

parallel | Two lines that always remain the same distance apart, they will never cross. |

perpendicular | Two lines that intersect forming right angles |

intersecting | Two lines that cross at a point |

diagonal | A segment that connects two non-adjacent points on a figure. |

angle | The shape formed when two rays intersect. |

acute angle | an angle that measures less than 90 degrees |

obtuse angle | an angle that measures between 91 and 179 degrees. |

straight angle | an angle that measures 180 degrees |

right angle | an angle that measures 90 degrees |

angle bisector | a ray that divides an angle into two equal sides |

complementary angles | two angles together that equal 90 degrees |

supplementary angles | two angles together that equal 180 degrees |

equilateral triangle | a triangle that has three equal sides and they all equal 60 degrees |

scalene triangle | a triangle that has no equal sides |

isosceles triangle | a triangle that has two equal sides and two angles |

right triangle | a triangle that has a right angle (90 degrees) |

acute triangle | a triangle that has angles that are less than 90 degrees |

obtuse triangle | a triangle that has an angle that is more than 90 degrees |
