Produktbeschreibung

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Reflection symmetry, reflectional symmetry, line symmetry, mirror symmetry, mirror-image symmetry, or bilateral symmetry is symmetry with respect to reflection. In 2D there is an axis of symmetry, in 3D a plane of symmetry. An object or figure which is indistinguishable from its transformed image is called mirror symmetric (see mirror image). Also see pattern. The axis of symmetry or line of symmetry of a two-dimensional figure is a line such that, for each perpendicular constructed, if the perpendicular intersects the figure at a distance ''d'' from the axis along the perpendicular, then there exists another intersection of the figure and the perpendicular, at the same distance ''d'' from the axis, in the opposite direction along the perpendicular. Another way to think about it is that if the shape were to be folded in half over the axis, the two halveswould be identical: the two halves are each other''s mirror image. Thus a square has four axes of symmetry, because there are four different ways to fold it and have the edges all match. A circle has infinitely many axes of symmetry, for the same reason.
