Acioms are only viewed as true because they are defined as such.<p>It&#x27;s obvious when applying math to real world. If you&#x27;re talking about objects on Earth surface, for example, at first Euclid&#x27;s geometry will get you good results, because objects you&#x27;re working with can be assumed to fulfill it&#x27;s axioms. However, when your scale gets bigger, you&#x27;ll have apply a more complicated geometry apparatus.<p>Easiest analogy about axioms is interface in software engineering: you don&#x27;t care what the object really is, but as long as it shows certain properties, you can prove theorems about it. Which will be true for any objects with these properties, and as true as exactly these properties are fulfilled by the real life object.
