Name of all polygons until 12 sides. Move the mouse over the shapes to discover their properties. Triangle Square Pentagon Hexagon Heptagon Octagon Nonagon Decagon Hendecagon Dodecagon These shapes are known as regular polygons. A polygon is a many sided shape with straight sides. To be a regular polygon all the sides and angles must be the same.

Endecagon (or hendecagon) and dodecagon.
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.

Endecagon (or hendecagon) and dodecagon.
triangle is first of all a polygon i.e. a shape with many sides so there are many other shapes and they are named by the number of sides they have like 4 sides-quadrilateral 5-pentagon 6-hexagon 7-heptagon 8-octagon 9-nonagon 10-decagon 12-dodecagon similarly there are circles which have no sides at all.
name of a polygon with 12 sides = dodecagon

Depending on their shapes and sizes, you can get a different trapezium, or plane shapes with up to 12 sides.
Proportional side lengths refer to the relationship between the sides of two similar shapes. If two shapes have proportional side lengths, it means that corresponding sides of the shapes are in the same ratio. For example, if one shape has sides of lengths 2, 4, and 6, and a similar shape has sides of lengths 4, 8, and 12, the sides are in proportion since the ratios 2:4, 4:8, and 6:12 are all equal.
A 3-dimensional shape (polyhedron) can have an unlimited number of faces. However, regular shapes (all sides identical) rapidly approach a spherical form beyond about 12 to 20 sides.
A laptop consists of two shapes, each an approximate cuboid, that are hinged together. If they were exact cuboids, the answer would be 12 sides. But they are not. The "sides" are curved, which complicates matters.
There are many shapes that have 12 sides. For example: A pyramid with a hendecagon (-sided) base; a decagonal prism; a hexagonal dipyramid; a dodecahedron, and many other shapes. Without information about what the shape is, and the lengths of its sides, it is impossible to even attempt to answer the question.
