In geometry, an object exhibits symmetry if it looks the same after a transformation, such as reflection or rotation. Symmetry is important in art, math, biology and chemistry.

But there are other kinds of symmetry, too. If you have a horizontal line and you shift horizontally, ... moving backwards in time). If the mirror reflection under all three (C, P, ...

The equation of the line of symmetry; Rotation; ... (y = 1\) is a horizontal line which passes through 1 on ... The equation of the mirror line is needed to fully describe a reflection. Next page.

2. Maths is beautiful. Folding is often based on maths and has many applications in engineering, medicine and science. The pattern that forms the Lumifold lamp is called a glide reflection.
