In (Schmidt and SteinitZ,-1996); an affine plane with Jixed basis ~I ,t2,0}is coordinated. Then, a ternary operation T on R which is a set of pointson I which is dependent on the coordinate system 11,/2, t is deJined. Inaddition, two different binary operation denoted by +,. on R using ternaryoperation T. After then, it is showed that (R,+,.) is a division ring. Inthis paper, Jirst of all we examined the relation between (R, T) ternary ringand Desargues postulate in aJine plane. After then, we showed that (R,+,.)is Jield in case affine plane satisfies Pappus Theorem. This results appearedin theJirst author's Msc thesis.
