In this way we could find some relations between special points of a triangle (orthocentre H, centre of gravity S, circumcentreM, midpoint F of the nine-point circle) and the radical centres of special triples of circles.application/pdfgeometry of trianglesremarkable points of a triangleradical centre of three circlesfolyóiratcikkOpen AccessOswald Gieringhttps://doi.org/10.5485/TMCS.2005.0073Teaching Mathematics and Computer Science23Teach.
