This construction is based on the aforementioned principle to maintain the distance (not the angles) between the vertices of a cube.[br][br]This way, an articulated cube is obtained, where its faces are not necessarily flat, but consist of hinges formed by two isosceles triangles. The possible positions of its vertices become difficult to analyze without resorting to this method [[url=https://www.geogebra.org/m/sw2cat9w#material/er8nf4qt]4[/url], [url=https://www.geogebra.org/m/sw2cat9w#material/er8nf4qt]5[/url], [url=https://www.geogebra.org/m/sw2cat9w#material/er8nf4qt]32[/url]].
