Abstract :In this paper, the first-order ODEs which have no systematic way to find their Lie point symmetries -unlike higher order ODEs which have systematic ways- are reconsidered. As a first step, we considered first order PDEs which correspond to these equations by introducing reduced characteristic Q that used in the Lie’s theory. Following this step, we tried to obtain solutions of the PDEs using their Lie point symmetries. But in this process, we met some difficulties, so by taking into account some assumptions we obtained the symmetries of ODEs which are in the special form, and also their solutions.Keywords : Lie point symmetry, Ordinary differential equations, Ricatti differential equations, scale symmetry, prolonged infinitesimals
