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 triangle
4 quadrilateral (a regular quadrilateral is a square)
5 pentagon
6 hexagon
10 decagon
12 dodecagon
20 Icosagon
90 enneacontagon
After 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.
There is no specific name for such shapes.

These are called polyhedrons, and their names are from the Greek word for the quantity (number) of faces (sides) on each shape. All faces are exactly the same as each other on regular polyhedrons; one or more faces are different from the other faces on irregular polyhedrons. A few of the countless number of polyhedron names, with the name following the number of faces on the 3d shape are:4 tetrahedron (a regular tetrahedron is a pyramid with 3 sloping sides and a base)5 pentahedron (a regular pentahedron is a pyramid with 4 sloping sides and a base)6 hexahedron (a regular hexahedron is a cube, having 4 sides, a top, and a base)10 decahedron12 dodecahedron24 icositetrahedron90 enneacontahedron
pentagon
The two quadrilaterals are squares.
There is no standard formula since a polyhedron can have a number of different shapes. A hexahendron, for example, can be a cuboid (6 rectangular faces) or a triangular dipyramid (6 triangular faces) or others. The number of different shapes increases rapidly as the number of sides (which determines the name) increases. The only solution is to calculate the area of each face and add them together.
There is no specific name for such shapes.
No. A triangle has 3 of each, whereas a square has 4 of each.
An hexagon has 6 sides
Shapes that only have straight edges are called polygons. Polygons can have various numbers of sides, such as triangles (three sides), quadrilaterals (four sides), pentagons (five sides), and so on. Each type of polygon is classified based on the number of sides it has, and they can be regular (with equal sides and angles) or irregular.

Shapes that do not have four sides include triangles, which have three sides; circles, which have no sides; and polygons like pentagons and hexagons, which have five and six sides respectively. Additionally, three-dimensional shapes such as spheres and cubes also do not have four sides in the traditional sense. Each of these shapes has distinct properties and characteristics that differentiate them from quadrilaterals.
No, because there are shapes with each number from 3 to infinitely many sides and it is not possible to produce an infinitely long list in the finite amount of time that the solar system has got.

Shapes that have equal but opposite sides include parallelograms, such as rectangles and rhombuses. In these shapes, opposite sides are not only equal in length but also parallel to each other. Additionally, some quadrilaterals, like squares, also exhibit this property. These characteristics ensure that the shapes maintain symmetry and balance.
