Earth Science – Minerals Math - Geometry This set of crystal models includes seven systems. These include the six basic (cubic (isometric), hexagonal, tetragonal, orthorhombic, monoclinic, and triclinic), and a seventh (trigonal, or rhombohedral), which is a subdivision of the hexagonal system. This is sometimes shown as its own group based on the differences in their appearance from the hexagonal crystals. The activity includes a model of each crystal form, labels for each, and a math conne
