Reflection through the origin
Did you know?
In mathematics, reflection through the origin refers to the point reflection of Euclidean space R n across the origin of the Cartesian coordinate system. Reflection through the origin is an orthogonal transformation corresponding to scalar multiplication by − 1 {\displaystyle -1} , and can also be written … Zobraziť viac In geometry, a point reflection (point inversion, central inversion, or inversion through a point) is a type of isometry of Euclidean space. An object that is invariant under a point reflection is said to possess point … Zobraziť viac In two dimensions, a point reflection is the same as a rotation of 180 degrees. In three dimensions, a point reflection can be described as a 180-degree rotation composed with … Zobraziť viac When the inversion point P coincides with the origin, point reflection is equivalent to a special case of uniform scaling: uniform scaling with scale factor equal to −1. This is an example of linear transformation. When P does not coincide with the origin, point reflection is … Zobraziť viac • Point reflection across the center of a sphere yields the antipodal map. • A symmetric space is a Riemannian manifold with an isometric … Zobraziť viac The term reflection is loose, and considered by some an abuse of language, with inversion preferred; however, point reflection is widely used. Such maps are involutions, … Zobraziť viac Given a vector a in the Euclidean space R , the formula for the reflection of a across the point p is $${\displaystyle \mathrm {Ref} _{\mathbf {p} }(\mathbf {a} )=2\mathbf {p} -\mathbf {a} .}$$ In the case … Zobraziť viac The composition of two point reflections is a translation. Specifically, point reflection at p followed by point reflection at q is translation by the vector 2(q − p). The set … Zobraziť viac WebReflectionTransform. ReflectionTransform [ v] gives a TransformationFunction that represents a reflection in a mirror through the origin, normal to the vector v. …
Web30. jún 2011 · This kind of symmetry is called origin symmetry. An odd function either passes through the origin (0, 0) or is reflected through the origin. An example of an odd … WebIn point reflection, a shape is reflected over a specific point, usually that point is the origin. Reflection in the Origin: Reflecting a point in the origin, both the x-coordinate and the y-coordinate are negated (their signs are changed). In a Point reflection in the origin, the coordinate (x, y) changes to (-x, -y).

In Euclidean geometry, two-dimensional rotations and reflections are two kinds of Euclidean plane isometries which are related to one another. A rotation in the plane can be formed by composing a pair of reflections. First reflect a point P to its image P′ on the other side of line L1. Then reflect P′ to its image P′′ on the other side of line L2. If lines L1 and L2 make an angle θ with one another, then points P and P′′ will make an angle 2θ …
