Abstract: Number Frieze relationship to triangulated polygons were pre-
sented in 1973 by Conway and Coxeter. Since then additional pa-
pers and presentations have been done by others including Henry
in 2013. Conway and Coxeter’s 1973 publishing was 35 open ended
questions followed by answers while Dr. Henry’s work showed there
remain some additional details not yet presented. In this talk we will
show some properties of Number Friezes in the environment of a commutative number ring $R$ with identity. We will also prove Conway
and Coxeter’s main theorem showing the dual relationship between
triangulated polygons and closed positive integral Number Friezes.
