使用 tikzpictures 绘制两个三角形

Question

我想使用 tikzpicture 包绘制以下两个三角形。

有人可以告诉我怎么做吗？

非常感谢

Answer 1

\documentclass[border=3mm]{standalone}
\usepackage{tikz}
\usetikzlibrary{shapes.geometric,patterns.meta}
\begin{document}
   \begin{tikzpicture}[fillSt/.style={shape=regular polygon,regular polygon sides=3,draw,thin,pattern={Dots[radius=0.1pt,distance=0.5pt,angle=45]}}]
% triangle left
\node[fillSt](tr-1){};
\draw[thick] (tr-1.corner 2) -- (tr-1.corner 3) ;
%triangle right
\node[fillSt](tr-2) at (1,0){};
\draw[thick,line join=bevel] (tr-2.corner 2) -- (tr-2.corner 1) -- (tr-2.corner 3) ;
    \end{tikzpicture}
\end{document}

这个怎么样？

\documentclass{article}
\usepackage{tikz}
\begin{document}


\tikzset{every picture/.style={line width=0.75pt}} %set default line width to 0.75pt        

\begin{tikzpicture}[x=0.75pt,y=0.75pt,yscale=-1,xscale=1]
%uncomment if require: \path (0,300); %set diagram left start at 0, and has height of 300

%Flowchart: Extract [id:dp6901203222093623] 
\draw  [fill={rgb, 255:red, 155; green, 155; blue, 155 }  ,fill opacity=0.52 ] (135,109) -- (170,170) -- (100,170) -- cycle ;
%Shape: Rectangle [id:dp3827041707489245] 
\draw   (100,169) -- (170,169) -- (170,170) -- (100,170) -- cycle ;
%Shape: Rectangle [id:dp4124155250260684] 
\draw   (238.32,110.4) -- (273.12,171.14) -- (272.25,171.63) -- (237.45,110.9) -- cycle ;
%Flowchart: Extract [id:dp2714396375563397] 
\draw  [fill={rgb, 255:red, 155; green, 155; blue, 155 }  ,fill opacity=0.52 ] (238.32,110.4) -- (273.32,171.4) -- (203.32,171.4) -- cycle ;
%Shape: Rectangle [id:dp9059060773721866] 
\draw   (239.83,111.67) -- (204.18,171.91) -- (203.32,171.4) -- (238.97,111.16) -- cycle ;

\end{tikzpicture}
\end{document}

像这样吗？

pattern radius/.store in=\mcRadius, 
pattern radius = 1pt}
\makeatletter
\pgfutil@ifundefined{pgf@pattern@name@_088n0fwyr}{
\makeatletter
\pgfdeclarepatternformonly[\mcRadius,\mcThickness,\mcSize]{_088n0fwyr}
