This is a little bit like asking why a square has four sides. A regular pentagon is defined in such a way as to require that it has 5-fold rotational symmetry.

Why 5-fold rotational symmetry is not possible in cube?

A cube has 3-fold rotational symmetry, meaning it can be rotated by 120 degrees and still look the same. It does not have 5-fold rotational symmetry because the cube's faces are not oriented in a way that allows for that type of symmetry. The angles between the faces do not align with the requirements for 5-fold rotational symmetry.

What are the degrees of a Symmetry?

A two-fold symmetry has a 360 degrees rotation. A three-fold rotational symmetry, on the other hand, has 120 degrees, and on a horizontal axis, a symmetry has 180 degrees.


Does a clover have rotational symmetry and how?

Yes, because if you take a clover and fold it it will fold evenly like paper.


What shape has a two-fold rotational symmetry?

A shape with two-fold rotational symmetry looks the same after a rotation of 180 degrees. An example of this is a rectangle, which appears unchanged when rotated halfway around its center. Other shapes, like certain types of isosceles triangles and some polygons, also exhibit this symmetry. Essentially, any shape that can be flipped upside down and still match its original appearance has two-fold rotational symmetry.


Why does an octagon have rotational symmetry?

An octagon has eight-fold rotational symmetry, because rotation of octagon by 45 degrees (one-eighth of a full circle) produces a figure that is superimposible on (or congruent to) the original.
