It is NOT considered a universal truth. It used to be, because mathematicians considered it to be "self-evident", but more recently, mathematical systems both with and without the parallel axiom have been developed. It turns out the "non-euclidian geometries" are very useful. In the real world, the euclidian geometry does NOT apply - although in many cases it is a good approximation.
When you need to measure the distance between two objects (to install a dishwasher, for instance), the ruler postulate is no only helpful, but necessary.
A fjord is a real world example of a fjord! They exist in the real world.
It is an axiom necessary for the real numbers to form a field.
2 is a real world prime number.
glenn caverte bayot!...

An axiom is a basic mathematical truth used in proofs, outlined initially by Euclid. Axioms are self-evident and do not need to be proven, they can be combined and used logically to prove more complex mathematical concepts, especially in geometry. Example: "The shortest distance between two points is a straight line."
Pythagoras
An axiom is a self-evident truth that is not proven, only accepted, such as that for any two real numbers a and b, either a > b, a = b, or a < b.
The Equator is a real world example, being the circumference of the Earth.
the world is an oval so ab make a line so if you dived what you said by 2 it equals 3
It is an axiom necessary for the real numbers to form a field.
Of what?
where could you find a pentagon in the real world
