Name of Geometric Shapes

2D Shapes

3D Shapes

Tool to find the name of geometric shapes. Polygons are geometrical shapes in the plane 2D and polyhedra are geometric shapes in the space 3D

Answers to Questions

What is the name of a polygon with...?

Indicate to dCode the number of sides and it will find the name.

Example: 6: HEXAGON

Example: 12: DODECAGON

Here is the list as a table of all the different regular geometric shapes of the 2D plane (table of n-sided polygon names):

How to learn geometric shapes?

Some resources for children are great to learn shapes such as here (link)

What are the polygons with an axial symmetry?

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.

What are the polygons with a central symmetry?

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.
