Komal Pankhudi 6 years, 2 months ago

If a transversal intersect two parallel lines, the the sum of angles on the same side of transversal (co-interior angles) is always 180°.If a transversal intersect two lines, then the side where the sum of co-interior anglesis less than 180°,that side the lines will converge and intersect each other at a point when those lines are extended and the side where the sum of co-interior angles is more than 180° that side will diverge and cannot intersect each other at any point if extended. That's the euclid's 5th postulate. Thank you
