File Plane mirror.png thumb A ray diagram for a plane mirror A plane mirror is a mirror with a Plane mathematics plane reflective surface. For light Ray optics rays striking a plane mirror, the angle of Reflection physics reflection equals the angle of incidence. Thus a Collimated light collimated beam of light does not spread out after reflection from a plane mirror, except for diffraction effects. A plane mirror makes images of objects in front of it these images appear to be behind the plane in which the mirror lies. A straight line drawn from part of an object to the corresponding part of its image makes a right angle with, and is bisected by, the surface of the plane mirror. The image formed by a plane mirror is always virtual image virtual meaning that the light rays do not actually come from the image , upright, and of the same shape and size as the object it is reflecting. A virtual image is a copy of an object formed at the location from which the light rays appear to come. However, the image is a laterally inverted mirror image of the object. If a person is reflected in a plane mirror, the image of his right hand appears to be the left hand of the image. Relation to curved mirrors Mathematically, a plane mirror can be considered to be the Limit mathematics limit of either a concave or a convex spherical curved mirror as the radius, and therefore the focal length , becomes infinite.

Plane symmetry means a symmetry of a pattern in the Euclidean plane that is, a transformation of the plane that carries any directioned lines to lines and preserves many different distances. If one has a pattern in the plane, the set of plane symmetries that preserve the pattern forms a group mathematics group . The groups that arise in this way are plane symmetry groups and are of considerable mathematical interest. A symmetry plane is a three dimensional object s symmetry axe. There are several kinds of plane symmetry groups Reflection group s. These are plane symmetry groups that are generated by reflections, possibly limited to reflections in lines through the origin. Circle group Rotation group s. These groups consist of rotations around a point. Translation group s. Symmetries of geometrical figure s.

Image BullnoseShoulderPlane.jpg thumb right 250px A bullnose shoulder plane. In this model the mouth is adjusted by adding or removing shim engineering shims behind the removable nose. The shoulder plane is a plane tool plane tool with a blade flush with the edges of the plane, allowing trimming right up to the edge of a workpiece. Like a rebate plane , the shoulder plane s blade extends, therefore cuts, to the full width of the tool. The shoulder plane is used to trim the shoulders and faces of Mortise and tenon tenons . It is used when it is necessary to trim right into the concave corner where two surfaces of the same piece of wood meet perpendicularly. It is also commonly used to clean up dadoes housings and tenons for joinery. Unlike the rebate plane, the shoulder plane is intended to cut end grain . There are therefore differences between it and a rebate plane in the angles at which the iron blade is set. There is a more acute angle between the iron and the sole of the tool. The iron is set square across the tool rather than obliquely. The iron is set face down. The ground and honed bevel forming the edge is uppermost. A shoulder plane also has a much finer set mouth, which allows finer shavings to be taken.

Unreferenced date December 2009 Image Strug katnik 03.jpg thumb 200px A rabbet plane The rebate plane also known as the rabbet plane is a hand plane designed for cutting rabbet rebates in wood. It s a simple tool, used in many Western countries, with hundreds of years of history. It was in use in England at least as early as the 11th century. The rebate plane is one of a group of planes including the shoulder plane , bullnose plane and carriage makers plane in which the blade protrudes by a very small amount usually less than half a millimetre from the sides of the plane body on both sides. The blade is very slightly wider than the body of the plane. The reason for the slight protrusion of the blade is so that the plane body does not bind on the side of the cut, which would result in the side wall of the rebate not being perpendicular to the bottom. Rebate planes are intended for long grain cutting and are generally setup to remove large amounts of material quickly. The mouth is set quite coarsely to allow large chips to be removed. There are a few variations of this plane, including the duplex rebate plane, which has two locations for the blade one in the middle of the body for normal cutting and one at the front to allow cutting into corners. In the latter mode, the duplex rebate plane is similar to a bullnose plane. The rebate plane commonly has a depth stop and a fence which allows the width and depth of the rebate to be gauged. They also are commonly equipped with a spur which is designed to score the wood as the rebate is cut, giving a cleaner corner. This is particularly valuable when working across the grain.

Unreferenced date December 2009 Image Strug zdzierak 01.jpg thumb 200px A scrub plane parts The scrub plane is a type of plane tool plane used to remove large amounts of wood from the surface of lumber, such as when eliminating cup or twist in the first stages of preparing rough stock, or when reducing the thickness of a board significantly. Scrub planes generally have a short soles, a relatively narrow but thick blade, a very wide mouth, and a deeply curved edge of about a 3  inch radius to make a deep, gouging cut. A scrub plane is generally used in diagonal strokes across the face of a board, rather than parallel to the length of the board along the grain as with most other bench planes. In thicknessing or preparing rough stock, the scrub plane is usually followed by the jack plane , jointer plane , then smoothing plane . Its function in modern woodworking has been largely replaced by power tools such as the thicknesser thickness planer . A scrub plane can still be useful for planing boards too wide to fit through a thickness planer.

Unreferenced date December 2009 A term used in celestial mechanics , the plane of reference is the plane by means of which orbital elements positions are defined. The two main orbital elements that are measured with respect to the plane of reference are the inclination and the longitude of the ascending node . Depending on the type of body being described, there are four different kinds of reference planes that are typically used Ecliptic or invariable plane for planets, asteroids, comets, etc. within the solar system , as these bodies generally have orbits that lie close to the ecliptic. Equator of orbited body for satellites with small semimajor axes Local Laplace plane satellites with intermediate to large semimajor axes Plane tangent to celestial sphere extrasolar objects On the plane of reference, a zero point must be defined from which the angles of longitude are measured.

In crystallography , a glide plane is symmetry operation describing how a reflection mathematics reflection in a plane, followed by a translation mathematics translation parallel with that plane, may leave the crystal unchanged. Glide planes are noted by a , b or c , depending on which axis the glide is along. There is also the n glide, which is a glide along the half of a diagonal of a face, and the d glide, which is along a fourth of either a face or space diagonal of the unit cell. The latter is often called the diamond glide plane as it features in the diamond structure. Formal treatment In geometry , a glide plane operation is a type of isometry of the Euclidean space the combination of a reflection mathematics reflection in a plane and a translation geometry translation in that plane ... in a plane and a translation in a perpendicular direction is a reflection in a parallel plane. However, a glide plane operation with a nonzero translation vector in the plane cannot be reduced like that. Thus the effect of a reflection combined with any translation is a glide plane operation in the general sense, with as special case just a reflection. The glide plane operation in the strict ... in up to three dimensions isometries in 3D . The isometry group generated by just a glide plane operation is an infinite cyclic group . Combining two equal glide plane operations gives a pure translation with a translation vector that is twice that of the glide plane operation, so the even powers of the glide plane operation form a translation group. In the case of glide plane symmetry , the symmetry group of an object contains a glide plane operation, and hence the group generated by it. For any symmetry group containing glide plane symmetry, the translation vector of any glide plane operation is one half of an element of the translation group. If the translation vector of a glide plane operation is itself an element of the translation group, then the corresponding glide plane symmetry ... more details

In mathematics, a Moufang plane , named for Ruth Moufang , is a type of projective plane , characterised by the property that the group of automorphisms fixing all points of any given line acts transitively on the points not on the line. In other words, symmetries fixing a line allow all the other points to be treated as the same, geometrically. Every Desarguesian plane is a Moufang plane, and as a consequence of the Artin Zorn theorem every finite Moufang plane is Desarguesian, but some infinite Moufang planes are non Desarguesian plane s. The projective plane over any alternative division ring is a Moufang plane, and this gives a 1 1 correspondence between isomorphism classes of alternative division rings and Moufang planes. The following conditions on a projective plane P are equivalent P a is Moufang plane. The group of automorphisms fixing all points of any given line acts transitively on the points not on the line. The group of automorphisms acts transitively on quadrangles. Any two ternary ring s of the plane are isomorphic. Some ternary ring of the plane is an alternative division ring. P is isomorphic to the projective plane over an alternative division ring.
