Stars are not regular shapes like geometric figures; instead, they are generally spherical due to the force of gravity pulling their mass towards the center. This shape is a result of hydrostatic equilibrium, where pressure from nuclear fusion in the core balances gravitational forces. However, some stars can exhibit irregularities or deformations due to factors like rotation or magnetic fields, but their overall structure remains predominantly spherical.
a regular star
A 'concave decagon' is a ten-sided shape with every other corner pushed in towards the centre. It forms a regular five-pointed star.
There is no such shape. A 2d shape with 5 sides and all equal angles must be a regular pentagon (or a 5-pointed star if you stretch the definition of "all angles"). And a regular pentagon - or star - has 5 lines of symmetry.
A regular pentagon if your talking external walls, internal lines is a 5 pointed star.
yes an eclipse is a regular shape

The same as they are now: a regular five-pointed star.
Not all are. Not only is it a concave shape, but the interior angles can vary. For a polygon to be regular, it must be equilateral and equiangular.

A star is not a specific shape: it is a generic word for a shape which has an even number of vertices. The interior angles at alternate vertices are usually reflex angles. A star can have six or more vertices.
no it isn't a regular shape
