Certain equalities and inequalities concerning polygons in ${\mathbb R}^2Mirko Radi\'cUniversity of Rijeka, Department of Mathematics, 51000 Rijeka, Omladinska 14, Croatia, email: mradic@ffri.hrAbstract: This article can be considered as an appendix to the article [R]. Here we mainly deal with $k$outscribed polygons, where we use the definition of such polygons as it is given in [R. The aim and purpose of the article is to find and investigate certain equalities and inequalities concerning $k$outscribed polygons.
