Abstract
We present in this work dynamic experiences that explore interesting geometric loci,such as Miquel points, Fermat points, Nagel points, and Gergonne points. In thesedynamic approaches, accessible through external links to pages on the GeoGebra platform,readers can change parameters through sliders and observe, as the parametersvary, whether the introduced changes satisfy the hypotheses that define the geometricloci. Additionally, we utilize GeoGebra to create two-dimensional geometric figures.In addition to providing definitions, we offer proofs of the theorems that establish theuniqueness of the covered geometric loci. Some of the proofs introduced in this workinvolve the concept of isotomic cevians, which needs more coverage in the existing literature.In summary, GeoGebra is an invaluable tool for constructing dynamic approachesto explore geometric loci. It empowers students to test hypotheses both before andafter formal demonstrations. One concludes that GeoGebra is a versatile software thatcan be effectively integrated into geometry education at all levels. Keywords: Isotomic cevians, Miquel’s point, Fermat’s points, Gergonne’s point, Nagel’spoint.
