It is not possible to name all of them since there are an infinite number of them.
The names of the common polygons by number of sides is as follows:
(1 = line, 2 = angle)
3 = triangle
4 = quadrilateral
5 = pentagon
6 = hexagon
7 = heptagon
8 = octagon
9 = nonagon or enneagon
10 = decagon
11 = undecagon or hendecagon
12 = dodecagon or duodecagon
20 = icosagon

How many faces does a 2D pentagon have?
all 2D figures have 1 face.
Do 2d figures have faces?
No, you are thinking about 3d figures
Volumes of 2-D dimensional figures?
2D figures have surface area, but no volume.
Does a 2D figure have an edge?
They have sides but 3D figures have edges
Does a 2D have edges or sides or both?
2d is 2 dimensional so there is only length and width... edges are only in 3d and 2d figures only have one side...
How are cubes different from squares?
Squares are 2D figures and cubes are 3D figures Also squares are the faces of a cube
Which shapes are 2d figures?
Circles, rectangles, squares, pentagons, etc.
Why are 1D figures important in the real world?
1D figures are important in the real world because if we did not have 1D figures, the we wouldn't be able to make 2D and 3D figures.
Factoring by grouping ac plus 2ad plus 2bc plus 4bd?
ac + 2ad + 2bc + 4bd (ac + 2ad) + (2bc + 4bd) group the figures a(c + 2d) + 2b(c + 2d) remove the common divisors of each set (a + 2b)(c + 2d) take the figures in parentheses as one set, and add the outside figures as the other
What is 2 different polygon shapes have 7 sides?
Polygons are 2D plane figures. All polygons with 7 sides would be classified as heptagons.
All 2d shapes with pictures?
it is all the 2d shapes with pics
What does 2d in maths mean?
2d means 2 dimensional or flat figures. If you are dealing with algebra or graphing, it would mean X and Y coordinates only, not Z.
