## Chart of Lines

Term | Symbol | Looks Like | Description |
---|---|---|---|

Points | Identify a position. Represented by dots. | ||

Lines | Lines are made up of a set of points. A line goes on forever in both directions. | ||

Rays | A____B_> (missing image) | A ray is a part of a line with one endpoint. | |

Line Segment | A___B (missing image) | A line segment is part of a line with two end points. | |

Angle | < ABC or < CBA | Formed by ray or line segments with a common endpoint. Endpoint is the vertex. | |

## Other Lines

Question | Answer | Column 3 |
---|---|---|

Parallel | Parallel Lines are two lines that never intersect. | |

Intersecting | Intersecting Lines are lines that cross each other at exactly one point, called the point of intersection. | |

Perpendicular | Perpendicular Lines are two lines that form a right angle at their point of intersection. | |

## Chart of Angles

Classification | Angle Measures | Diagram | Angle Names |
---|---|---|---|

Acute | Less than 90 degrees | < ABC = 30 degrees OR < CBA = 30 degrees | |

Right | is 90 degrees | < DEF = 90 degrees OR < FED = 90 degrees | |

Obtuse | Between 90 and 180 degrees | < GHI = 125 degrees OR IHG = 125 degrees | |

Straight | Is 180 degrees | J.____K.___L. (missing image) | < JKL = 180 degrees OR < LKJ = 180 degrees |

Reflex | Between 180 and 360 degrees | < MNO = 330 degrees OR < ONM = 330 degrees | |

Complementary | Angles that up to 90 degrees. | < ABD + < DBC = 90 degrees (example) | |

Supplementary | Angles that up to 180 degrees. | < ABD + < DBC = 180 degrees(example) | |
