Indicate to dCode the number of sides and it will find the name.
Example: 6: HEXAGON
12: DODECAGON
More generally, polygons are written with a prefix indicating their number of sides and the suffix -gon.
Here is the list as a table of all the different regular geometric shapes of the 2D plane (table of n-sided polygon names):

Indicate the number of faces and it will find the name of the 3D geometrical figure.

Example: 12: DODECAHEDRON
Here is a table of all the regular geometric shapes/polyhedron of 3D space (table of names of n-faced polyhedra):
Some resources for children are great to learn shapes and other geometric figures such as here (link)
All regular polygons have at least one axial symmetry.
A regular polygon with as many axes of symmetry as it possesses sides.
The axes of symmetry pass through the center of the polygon and the center of each side or each vertex/corner.
All regular polygons with an even side number have a central symmetry (the center of the polygon). Polygons with an odd number of sides have no central symmetry.
A polytope is the generalization of a polygon / polyhedron to all dimensions.
