Resumen de Exploring dissections of rectangles into right-angled triangles

Martin Griffiths

• In this article we highlight how a simple classroom activity associated with the dissection of rectangles into right-angled triangles can lead on to a number of interesting explorations for students following a post-16 mathematics course. Several results connected with this construction are obtained, and some of the educational benefits of carrying out an investigation such as this are also discussed.
