Abstract

The article is focused on investigation of geometric loci by current dynamic geometry software. On a few problems we illustrate ability of actual software to determine an unknown locus and its equation in terms of given properties using GeoGebra commands Locus and LocusEquation. After the use of these commands we present how computer arrives at the searched locus and how to analyze the cases when we get some extra components apart from the locus, either due to degenerate instances of the construction or due to Zariski closure of an algebraic set. We also demonstrate the ways how to attain new results by experiments, which would be hardly accessible without computers.
