  • 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

  • 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
