This allows first to visualize the shape of the geometric locus, then to state a conjecture to validate a solution founded by analytical geometry methods. The search for a geometric locus using GeoGebra software makes the activity more attractive. %K Open Source Software %K GeoGebra %K Orthocenter %K Analytical Geometry %U http://www.oalib.com/paper/5436014
