    Observation related to Euclid's Fifth Postulate: 1. If the sum of the interior angles is less than 180 degrees, then the two lines will eventually intersect. 2. If the sum of the interior angles is 180 degrees, then the two lines are parallel and will never intersect. 3. If the sum of the interior angles is greater than 180 degrees, then the two lines will never intersect.

      Good observation

    • @kamleshdhingra6564

      If the lines are not parallel they will surely intersect , so the observation is correct but in third point the lines in one direction can never intersect but in other direction it can intersect because if they will never meet it and also not parallel means once they have already met , we can check that by extending them and in one direction we will see that they can intersect

    • @dostotussigreatho
      @dostotussigreatho  4 года назад

      Hi Prakashddm,
      Parallel lines never intersect because they always maintain same distance between them. Similarly, intersecting lines can never be parallel.

      For "universal truth", wow, that's an interesting question. I would say that anything or any fact that is universally (worldwide) accepted as TRUE is "universal truth" i.e. something like - sun rises from the east. Hope it helps!
