Abstract

In this paper non-tangential quadrilaterals in the isotropic plane are studied.
A quadrilateral is called standard if a parabola with the equation
$x=y^2$ is inscribed in it. The properties of the standard
quadrilateral related to the focus and the median of the
quadrilateral are presented. Furthermore, the orthic of the
quadrilateral is introduced.

Keywords

isotropic plane; non-tangential quadrilateral; parabola; focus; median; orthic
