Torus facts for kids

A ring torus

A Torus is a shape from geometry that is obtained by rotating a circle in 3D space. To obtain a torus, the point around which the rotation occurs must be in a plane with the center of the circle. If the point of rotation lies outside the circle, the shape of the torus will have a hole, and the torus will be called ring torus.

• 

  The configuration space of 2 not necessarily distinct points on the circle is the orbifold quotient of the 2-torus, T2/S2, which is the Möbius strip.

• 

  In three dimensions, one can bend a rectangle into a torus, but doing this typically stretches the surface, as seen by the distortion of the checkered pattern.

• 

  A toroidal polyhedron with 6 × 4 = 24 quadrilateral faces

• 

  This construction shows the torus divided into seven regions, every one of which touches every other, meaning each must be assigned a unique color.
