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."
Such statements are called postulates in geometry and axioms in other areas. Definitions are also accepted without proof, but technically they are abbreviations rather than statements.
There is not a proof of purchase on Marley and Me. If you are doing the rebate, it says you need the proof of purchase - well I just called and the nice lady said that as long as the receipt has the name "Marley" on it, that is enough. Not sure why they lack a proof of purchase. Hope this helps.
you don't actually nee papers, you need need about two forms of id to show proof of your age . but you will have to fill out an American idol release form.
You do need proof of your age (16+) if you look young-ish but if you are a grown adult then it will be obvious that you don't need it. :)
Axioms, or postulates, are accepted as true or given, and need not be proved.
Axioms and Posulates -apex
This isn't really the answer you're looking for, but it turns out that axioms do not need to (and in fact CANNOT) be proven. And each proposition has a unique proof, unfortunately.
I don't know what you mean by solving logical deduction. Do you mean how do you tell, given an allegedly logical deduction, whether it really is logical? Or do you mean, given a theorem, how do you logically prove it, that is, prove that it logically follows from the axioms? The last question is very complicated. Some theorems have taken centuries to prove (like Fermat's last theorem and the independence of Euclid's Parallel Postulate), and some have not yet been proven, like the Goldbach conjecture and Riemann's hypothesis. The first question is much simpler, but to describe exactly how to verify the validity of a deduction, we would need to know what kind of deduction it is. For example, a deduction involving only logical connectives like and, or, if-then, not can be verified with a truth table. Those involving quantification or non-logical symbols like set membership require looking at the proof and seeing that each step can be justified on the basis of the axioms of the system, whether it is the system of Euclidean Geometry, of the field of real numbers, or of Zermelo-Frankel Set Theory, etc.

The question is not logical. You need to clarify what is your question.
Yes - if such a counterexample can be found. However, using only the Euclidean axioms and logical arguments, it can be proven that the angles of a triangle in a Euclidean plane must add to 180 degrees. Consequently, a counterexample within this geometry cannot exist.

you need proof

A logical statement is one that will return a boolean or a logical "True" or "False" output. It is used in cases where conditions need to be executed. For ex: lets say you write a system that checks the age of the visitors to a bar, the system should only allow people who are over 18 yrs of age. So the logical condition will be like below: if(age > 18) then "Let the Customer Enter" else "The customer is a minor, send them back to stay out of trouble"
The need for PROOF. Hypothesis, is a thoery without proof. 'Hypo' Classical Greek for 'Under/ Less than' & 'thesis' a thoery . A Theory has a PROOF , that it is universally accepted by one's peers.
