There are infinitely many of them so it is not possible to list their names. If the sides are all straight lines, they are collectively called polygons.

All regular polygons with an even number of sides. Irregular polygons with an odd number of sides can have parallel sides. There are also non polygonal shapes that can have parallel sides.
All regular polygons (in order of sides starting with 3 sides): triangle, square, pentagon, hexagon, octagon, nonagon, decagon, hendecagon, dodecagon, tridecagon, tetradecagon, pentradecogon, hexadecagon, octadecagon, enneadecagon, icosagon (twenty sides).2d shapes are shapes that can be drawn on a paper, like lines, triangles, squares, rectangles, circles, etc. Some of these shapes are called polygons, and there are countless numbers of them with their names based on the Greek word for the number of sides on each shape. All sides are exactly the same as each other on regular polygons; one or more sides are different from the other sides on irregular polygons. A few of the polygon names, with the name following the number of sides on the 2d shape are:3 triangle4 quadrilateral (a regular quadrilateral is a square)5 pentagon6 hexagon10 decagon12 dodecagon20 Icosagon90 enneacontagonAfter about 10 sides mathematicians usually refer to polygons as n-gons; a 12 sided polygon (dodecagon) could also be called a 12-gon.In addition to polygons, there are circles, ovals, parabolas, and many other shapes that do not have straight sides.
Regular shapes:all sides and angles are the same Irregular shapes: different angle and sides
Polygonal (2-d) shapes get their (not there) names from the number of sides; polyhedra (3-d) shapes get their names from the number of faces.The names of other shapes: circles, ellipses, torus, cardioid etc have different origins.
Polyhedra.
A shape is an object with a specific number of sides. Some examples of shapes include circles, squares, triangles, pentagons, and hexagons.
There are infinitely many of them so it is not possible to list their names. If the sides are all straight lines, they are collectively called polygons.

Names for shapes that have equal sides are called EQUILATERAL.
rhombus
All regular polygons with an even number of sides. Irregular polygons with an odd number of sides can have parallel sides. There are also non polygonal shapes that can have parallel sides.
You specify shapes by the number of sides (or edges, different name) they have. The suffix -gon at the end of a word show how many sides it has in the words. For example, an octagon has eight sides; so if you see a shape with eight sides, it's an octogon. All shapes are known as polygons, which means it has three or more sides.
2d shapes that do not have equal sides do not usually have special names.

There is no special name to distinguish shapes with more than 14 sides from those with 14 or fewer.
