"Defined items" are defined in terms of "undefined terms".

It is a very basic concept which cannot be defined. Undefined terms are used to define other concepts. In Euclidean geometry, for example, point, line and plane are not defined.
The difference between defined and undefined terms is that the defined terms can be combined with each other and with undefined terms to define still more terms. These are undefined terms: 1.plane 2.point 3.line These are defined terms: 1.ray 2.union of sets 3.space 4.subset 5.set 6.proper subset 7.opposite rays 8.postulate 9.betweenness of points 10.bisector of a segment 11.midpoint of a segment 12.line segment 13.lenght of a segment 14.collinear points 15.complement of a set 16.coplanar points 17.disjoint sets 18.element 19.empy set 20.finite set 21.geometry 22.infinite set 23.intersection of sets
Image result for In an axiomatic system, which category do points, lines, and planes belong to? Cite the aspects of the axiomatic system -- consistency, independence, and completeness -- that shape it.
physical representation of undefined terms in real life?
There are Four building blocks of geometery. They are; theorems, postulates, definitions, and undefined terms. They are terms that prove statements in geometery. The undefined terms include a point, line and plane.
