Acute Angle | An angle that measures less than 90 degrees. |

Obtuse Angle | An angle that measures more than 90 degrees but less than 180 degrees. |

Right Angle | An angle that measures exactly 90 degrees. |

Straight Angle | An angle that measures exactly 180 degrees. A straight line. |

Complementary angles | Two angles that together equal 90 degrees (right angle). They also share a vertez and a ray. |

Supplementary angles | Two angles that share a vertex and a ray; together they form a straight angle (180 degrees). |

Point | An exact location in space, usually represented by a dot. |

Line | A straight path in space, extending in both directions with no endpoint. |

Ray | A part of a line, it hegins at an endpoint and extends forever in one direction. |

Intersecting lines | Lines that cross each other at exactly one point. |

Parallel lines | Lines in a plane that will never intersect. |

Perpendicular lines | Two lines that intersect to form right angles. |

Vertex | The point where two rays join to form an angle. |
