Abstract

Zusammenfassung Das Heidelberger Winkelkreuz ist ein Werkzeug zur enaktiven Untersuchung geometrischer Figuren. Es besteht aus zwei Holzleisten, die mittig drehbar miteinander verbunden sind. Auf den Holzleisten befinden sich in äquidistanten Abständen Stifte. Mittels eines Gummis lassen sich auf dem Heidelberger Winkelkreuz Repräsentanten geometrischer Figuren spannen. Im Artikel wird aufgezeigt, in welcher Art und Weise die Betrachtung konvexer Vierecke mittels des Heidelberger Winkelkreuzes systematisiert wird und warum und wie derartige Untersuchungen in den Mathematikunterricht allgemeinbildender Schulen integriert werden können.
