5. If a straight line falling on twostraight lines makes the interiorangles on the same side of it suchLthat their sum is less than tworight angles, then the two straightlines, if produced indefinitely.meet on that side on which thesum of angles is less than tworight angles. In the given fig.,the line ST falls on the lines LM and PQ such that the sum of theinterior angles 1 and 2 is less than 180° (on the left side of ST)Therefore, the lines LMand PQ will intersect on the left side of STNS
