For example, suppose we rotate an angle around the origin by 90 in the counterclockwise direction. Halmos, "Finite-dimensional vector spaces", v. To rotate an angle means to rotate its terminal side around the origin when the angle is in standard position. Artmann, "Lineare Algebra", Birkhäuser (1986) Reflection in math definition is the mirror image of a figure over a line. Reflection math dictionary - A transformation in which a geometric figure is. reflection definition in geometryTransformation Geometry Definition with. Greenberg, "Euclidean and non-euclidean geometry", Freeman (1980)ī. Reflection Definition A reflection in geometry is a mirror image of a. The line that you reflect across is called the line of reflection. Coxeter, "Introduction to geometry", Wiley (1963) A reflection is another type of basic rigid motion. Berger, "Geometry", 1–2, Springer (1987) (Translated from French) Rosenfel'd, "A history of non-euclidean geometry", Springer (1988) (Translated from Russian) Glide reflection is a type of transformation of geometric figures, where two types of transformations (reflection and translation) are combined to 'slide' and 'flip' a figure. The spelling reflexion also occurs in the literature.Ī basic fact is that the reflections generate the orthogonal group see, Sects.
Note: A horizontal reflection has a vertical axis of reflection. Rozenfel'd, "Non-Euclidean spaces", Moscow (1969) (In Russian) A reflection in which a plane figure flips over horizontally. Reflection is a type of transformation that flips a shape in a mirror line (also called a line of reflection) so that each point is the same distance from the. Gottschling, "Reflections in bounded symmetric domains" Comm. Vinberg, "Discrete linear groups generated by reflections" Math. Bourbaki, "Groupes et algèbres de Lie", Eléments de mathématiques, Hermann (1968) pp. Every biholomorphic automorphism of finite order of a bounded symmetric domain in a complex space the set of fixed points of which has a complex codimension 1 is also called a unitary reflection. Is a pseudo-reflection of finite order (not necessarily equal to 2), then $ \phi $ Is the field of complex numbers and $ \phi $ Is dropped, then the more general concept of a pseudo-reflection is obtained. Of an $ n $-dimensional simply-connected space $ X ^ $
