What is monoclinic symmetry?
Monoclinic systems have point symmetry of 2, m, or 2/m, all of which require two of the unit cell axes to be oriented at right angles to the third axis in order for a two-fold rotation or mirror to be compatible with the translational symmetry of the lattice.

Is orthoclase monoclinic or triclinic?
Sanidine and orthoclase are monoclinic or nearly so; the plagioclase feldspars are triclinic.

What is the monoclinic crystal system?
In crystallography, the monoclinic crystal system is one of the practical crystal systems. Three vectors describe a crystal system. In the monoclinic system, the quartz is described by vectors of inequitable lengths, as in the orthorhombic system forming a rectangular type prism with a parallelogram base. Hence two combinations of vectors are perpendicular (join at right angles), while the third pair forms an angle other than 90°.
What are the three axes of the monoclinic system?
Well, crystalline solids can be categorized according to the structure of crystals. In the monoclinic system, crystals are referred to mainly three axes, a, b, and c, where axes a is perpendicular to axes b and c, but simultaneously, a and b are not perpendicular to each other. Suppose atom groups or atoms in crystalline solids are represented by points and lattices when points are connected with each other. The monoclinic unit cell is differentiated by a single axis called two-fold symmetry, where the monoclinic unit cell can be rotated by 180 degrees without disturbing appearance. Some of the solids that belong to the monoclinic crystal system are borax, gypsum, beta-sulfur, orthoclase, muscovite, kaolin, clinoamphibole, azurite, jadeite, and spodumene.
What is Crystallography and its Types?
Crystallography is the study of the arrangement of bonds of atoms in crystalline solids. In this system, mainly atoms arrangement is studied based on the crystal lattice. In modern days, DNAs and minerals are examined through crystallography. Well, many kinds of crystal systems are used nowadays. All the structure is defined based on three factors: how many axes used, length, and angles of the axis.
What is cleavage in crystals?
Answer: Cleavage is referred to the ability of any mineral to break atomic planes of weakness. In the monoclinic crystal system, many crystals have distinct cleavage in one of the three directions. For example, realgar, crocoite, gypsum, orpiment, spodumene, orpiment, diopside, muscovite and orthoclase. But all the minerals are not the same as lazulite. Lazulite is an exception to the cleavage in the monoclinic system, and it is a very known mineral. Lazulite has very poor, or we can say indistinct cleavage in one of the three directions. Cleavage is dependent upon how the atoms are arranged in the mineral. In addition, cleavage is not measured with any particular numbers but it can be good, normal, weak, or excellent.

What is the shape of a monoclinic prism?from en.wikipedia.org
In the monoclinic system there is a rarely used second choice of crystal axes that results in a unit cell with the shape of an oblique rhombic prism; it can be constructed because the rectangular two-dimensional base layer can also be described with rhombic axes. In this axis setting, the primitive and base-centered lattices swap in centering type.
