⚘If a straight line l falls on the two straight lines m & n such that the sum of the interior angles on one side of l is two right angles , then by Euclid's fifth postulate the lines will not meet on the sides of l . So the lines m & n never meet and are therefore parallel.
In geometry, the parallel postulate, also called Euclid's fifth postulate because it is the fifth postulate in Euclid's Elements, is a distinctive axiom in Euclidean geometry.
