I dont know about this...but i will give you an answer.From  a book

anonymous · Answer

ok

anonymous · Answer

same side interior angles of  are supplementary,.  Then, by the parallel axiom, L and M do not intersect because the interior angles on each side of the transversal equal  180º, which, of course, is not less than 180º.  So, because they do not intersect on either side (both sides' interior angles add up to 180º), than have no points in common, so they are parallel.

anonymous · Answer

or actually...logic

anonymous · Answer

If we know that interior angles=180, then we know that there can exist only two possibilities:  either the lines do not intersect at all (and hence are parallel), or they intersect on both sides.  However, lines L and M could not intersect in two places and still be distinct.  This would be impossible, since two points determine a line.  Therefore, L||M.
