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.

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


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.

How many lines of symmytrey does a pentagon have?

A pentagon has five lines of symmetry. Each line of symmetry passes through a vertex and the midpoint of the opposite side, dividing the pentagon into two equal halves. The lines of symmetry for a regular pentagon are evenly spaced at 72-degree angles from each other.
