What are the different number of sides shapes called?
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.
Where did shapes get their names?
from there sides
Which shapes have a parallel sides?
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.
What are some names of 2d shapes and the number of sides for each?
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.
How are regular and irregular shapes the same?
Regular shapes:all sides and angles are the same Irregular shapes: different angle and sides
