**Abstract:** This paper begins with weak assumptions and develops its conclusions from orthogonality and reflection, in conjugation with certain meta-theoretical arguments. The symmetry of orthogonality and certain reflection-geometrical representations are of particular interest.

Some lower levels of Euclidean planes are discussed.
