Is Computer Algebra Ready for Conjecturing and Proving Geometric Inequalities in the Classroom?

We introduce an experimental version of GeoGebra that successfully conjectures and proves a large scale of geometric inequalities by providing an easy-to-use graphical interface. GeoGebra Discovery includes an embedded version of the Tarski/QEPCAD B system which can solve a real quantifier elimination problem, so the input geometric construction can be translated into a semi-algebraic system, and after some algebraic manipulations, the obtained formula can be translated back to a precisely stated geometric inequality. We provide some non-trivial examples to illustrate the performance of GeoGebra Discovery when dealing with inequalities, as well as some technical difficulties. [ABSTRACT FROM AUTHOR]
