  Properties of the logical reloading in the Euclidean geometry are considered.
The logical reloading is a logical operation which replaces one system of basic
concepts of a conception by another system of basic concepts of the same
conception. The logical reloading does not change propositions of the
conception. However, generalizations of the conception are different for
different systems of basic concepts. It is conditioned by the fact, that some
systems of basic concepts contain not only propositions of the conception, but
also some attributes of this conception description. Properties of the logical
reloading are demonstrated in the example of the proper Euclidean geometry,
whose generalization leads to different results for different system of basic
concepts.
