Abstract

We show that every Jordan quadrilateral contains a disk so that contains points of three different sides of . As a consequence, together with some modulus estimates from Lehto and Virtanen, we offer a short proof of the main result obtained by Chrontsios-Garitsis and Hinkkanen in 2024 and it also improves the bounds on their result.
