Why is Axiom 5, in the list of Euclid’s axioms, considered a ‘universal truth’? (Note that the question is not about the fifth postulate.)
Axiom 5 : The whole is always greater than the part.
Take an example of a cake. When it is whole it will measures 2 pound but when we took out a part from it and measures its weigh it will came out lower than the previous one. So, the fifth axiom of Euclid is true for all the universal things. That is why it is considered a ‘universal truth’.
