  1. 1-3 Segments, Rays, Parallel Lines and PlanesM11.B.2, 2.5.11.BObjectives: 1) Identify segments and rays2) Recognize parallel lines

  2. Vocabulary • Segment- is the part of a line consisting of two endpoints and all points between them Ex) • Ray- is the part of a line consisting of one endpoint and all the points of the line on one side of the endpoint Ex) Endpoint Endpoint A B . . . . A B Endpoint AB AB **Must start with endpoint when naming a ray**

  3. Vocabulary • Opposite Rays – are two collinear rays with the same endpoint. Always form a line. . . . Q R S RQ and RS are opposite rays

  4. Example 1: Naming Segments & Rays • Segments: • Rays: . A . . B C

  5. Ex. 2: Naming Segments and Rays • Name the segments and rays. • LP and PL form a line, Are they opposite rays? • Which rays are opposite rays? L P Q

  6. Vocabulary • Parallel Lines – Are coplanar lines that do not intersect AB || EF • Skew Lines – Are noncoplanar, therefore, they are not parallel and do not intersect. AB and CG are skew C D A G F E

  7. Example: Identify Parallel & Skew Lines • Parallel to AB Skew to AB E F D C G A B

  8. Vocab • Parallel Planes – are planes that do not intersect. • Name two planes that are parallel. • Name a line that is parallel to BC. • Name a line that is parallel to plane BFGC E F A B G H D C

  9. Example: Identifying Parallel Planes • Name all segments parallel to AD • Name all segments skew to AD E F A B G H D C
