Magic of Centroids
Ferrarello, Daniela; Mammana, Maria Flavia; Pennisi, Mario
International Journal of Mathematical Education in Science and Technology, v49 n4 p628-641 2018
In this paper, we show some properties of centroids of geometric figures, such as triangles, quadrilaterals and tetrahedra. In particular, we will prove the properties by means of geometric transformations and by introducing extensions of triangles and quadrilaterals, i.e. by adding one, two or three new vertices to the figure. The study of these properties can be used, with profit, in a classroom activity supported by a dynamic geometry system.
