Crystal faces in crystal systems are defined by their size and angle, guided by principles like Steno's law. The hexagonal crystal structure illustrates how angles and side lengths shape crystal symmetry.
Crystal faces in crystal systems are defined by the characteristics of size and angle. The angles between corresponding faces on crystals are consistent for all specimens of the same mineral, a principle known as Steno's law.
Crystal systems are categorized into seven types, including cubic, tetragonal, orthorhombic, rhombohedral, hexagonal, monoclinic, and triclinic, each with unique angles and axes.
The hexagonal crystal structure exemplifies this, where two angles are 90°, while the third angle is 120°, with specified side lengths that contribute to the crystal's overall shape and symmetry.
