Abstract

This paper shows the necessary and sufficient condition for bicentrical polygons which are circumscribed and inscribed by two ellipses using Jacobian elliptic functions. Moreover the formulae for a bicentrical triangle, quadrilateral and pentagon are presented and the fact that these formulae are the necessary and sufficient conditions for bicentrical polygons is presented.
