A closed 2 dimensional shape is a polygon
A zero-dimensional shape is a point.
It has length and width but no height
Vertices are the points on any shape. For example, A 2-dimentional square has 4 vertices.
A two dimentional shape with 1 side and 1 vertex.

If it is a 2 dimentional shape it is called an 'octadecagon'
it is a flat surface... the opposite of 3-dimentional.
There is no such shape. If anyone can prove otherwise, I'd be grateful if they'd let me know.
They are polyhedra.

There are quite a few. Circles, squares, triangles...
a planet

A shape that it is 3D and has sides, corners and faces
A two dimentional shape with 1 side and 1 vertex.
