Abstract

Introduction

In two recent issues of the Learning & Teaching Mathematics journal, the following interesting area and perimeter formulae for an isosceles trapezium with an inscribed circle were derived and proven by the authors cited below:

In this article further interesting properties of an isosceles trapezium with an inscribed circle, as well as for a kite that is cyclic, will be derived. These two types of quadrilaterals have respectively been called ‘circumscribed isosceles trapeziums’ and ‘right kites’ in De Villiers (2009), and the same terminology will be used here.
