Categorical Aspects in Pasch Geometry
  In this study, after introducing Pasch geometries and algebraic properties of their, we studied categorical structure of the categories of Pasch geometries with morphisms and homomorphisms. In this regard, definition and construction of some categorical objects such as: equalisers, pullbacks, initial and terminal objects and products are given.
