TeX - LaTeX Asked by Nicolette Moucheron on September 1, 2021
I need to draw a graph with 10 nodes in LaTeX. I thought about doing it with tikz and try to give exact coordinates to draw a decagon but I don’t know what coordinates to give.
In this link you can find a series of regular polygons...I have changed the code to have the penthagon. Here the drawing is without coordinates.
documentclass[12pt]{article}
usepackage{tikz}
begin{document}
% Radius of regular polygons
newdimenR
R=1cm
This is a pentagon $n=10$,
begin{tikzpicture}
draw[yshift=-6.0R] (0:R) foreach x in {36,72,...,359} {
-- (x:R)
} -- cycle (90:R) node[above] {$scriptstyle n=10$} ;
end{tikzpicture}
that it could be used as a symbol.
end{document}

A solution with PSTricks only for either fun or comparison purposes.
curvepnodes
is useful to define an array of nodes for any given number of nodes and curve functions. For example, we can use it to make an array of 12 nodes on a circle. Offset
is provided as the rotation offset.
documentclass[pstricks,margin=5mm]{standalone}
usepackage{pst-node,pst-plot}
begin{document}
begin{pspicture}[showpoints,dotscale=1](-4,-4)(4,4)
pstVerb{/Offset 30 def}%
curvepnodes[plotpoints=11]{0}{360}{3 t Offset add PtoC}{A}
psnpolygon[linecolor=red](0,numexprAnodecount-1){A}
end{pspicture}
end{document}
documentclass[pstricks,margin=5mm]{standalone}
usepackage{pst-node,pst-plot}
begin{document}
multido{i=0+10}{10}{%
begin{pspicture}[showpoints,dotscale=6](-4,-4)(4,4)
pstVerb{/Offset ispace def}%
curvepnodes[plotpoints=13]{0}{360}{3 t Offset add PtoC}{A}
psnpolygon[linecolor=red](0,numexprAnodecount-1){A}
end{pspicture}}
end{document}
