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.

Why is Euclid axiom 5 considered to be universal truth?
Euclid's fifth axiom, often referred to as the Parallel Postulate, states that through a point not on a given line, there is exactly one line parallel to the given line. It is considered a universal truth because it establishes a foundational concept in Euclidean geometry, allowing for consistent reasoning about lines and angles. Its acceptance has led to the development of various geometric principles and theorems, which have stood the test of time in both theoretical and practical applications. Additionally, the exploration of alternatives to this axiom has spurred the creation of non-Euclidean geometries, further solidifying its significance in the mathematical landscape.
What is a real world example of a postulate or axiom?
an axiom is a fact/property such as "ac = ca"
What is the difference between and axiom and a postulate?
There is no difference - synonymous.
What other terms or pharse mean the same as postulate?
Terms that mean the same as "postulate" include "axiom," "assumption," "hypothesis," and "premise." These words all refer to a statement or proposition that is accepted as true without proof, serving as a foundational basis for further reasoning or argumentation.
Is every statement a theorem why?
There are many kinds of statement that are not theorems: A statement can be an axiom, that is, something that is assumed to be true without proof. It is usually self-evident, but like Euclid's parallel postulate, need not be. A statement need not be true in all circumstances - for example, A*B = B*A (commutativity) is not necessarily true for matrix multiplication. A statement can be false. A statement can be self-contradictory for example, "This statement is false".

What is another name for the Playfair Axiom?
Another name for the Playfair Axiom is the Euclid's Parallel Postulate. It states that given a line and a point not on that line, there is exactly one line parallel to the given line passing through the given point.
An axiom or a is an accepted statement of fact?
A postulate is assumed to be a fact and used to derive conclusions. However, there is no assurance that the postulate is itself true and so all the derived conclusions may depend on a proposition that is not necessarily true. Euclid's fifth, or parallel) postulate in geometry is a notable example.
Who restated Euclid's 5th postulate?
Probably the best known equivalent of Euclid's parallel postulate, contingent on his other postulates, is Playfair's axiom, named after the Scottish mathematician John Playfair, which states:In a plane, given a line and a point not on it, at most one line parallel to the given line can be drawn through the point.
What are synonyms of postulate?
Educated guess.
What is a real world example of a postulate or axiom?
an axiom is a fact/property such as "ac = ca"
What is another name for the parallel postulate?
Playfair Axiom
Another name for the Playfair Axiom?
parallel postulate
What is the difference between and axiom and a postulate?
There is no difference - synonymous.
Are two lines that are parallel to the same line parallel to each other?
Yes they are. It is delineated in something called the parallel postulate, and the axiom is also called Euclid's fifth postulate. This is boilerplate Euclidean geometry, and a link can be found below if you'd like to review the particulars.
What is a statement that is accepted as true without proof.?
A postulate or axiom
What is also called an axiom?
In classical studies, it is also called a postulate.
