Centrality Universality Definitions, Axioms, and Postulates The definitions are not mathematical and of no rigorous value. They can be thought of as giving intuition. Examples The five axioms are intended to be general principles, not specific to geometry. 1. Things that are equal to the same thing are equal to each other. 2. If equals be added to equals, the wholes are equal. 3. If equals be subtracted from equals, the remainders are equal. 4. Things that coincide with one another are equal to one another. 5.
