Line Segment | A set of points consisting of 2 points on a line called endpoints and all the points between these endpoints. |

Congruent Segments | Segments that have the same length |

Midpoint | The point of a segment that divides a segment into two congruent segments. |

Bisector of a Line Segment | Any line or subset of a line that intersects the segment at the midpoint. CUT IN HALF! |

Ray | Consists of an endpoint and all the points on that side |

Opposite Rays | Two rays of the same line that share the same and point and no other point. |

Angle | A union of 2 rays with one common endpoint |
