步骤、线条、tikzpicture

Question

嘿，有人可以帮我根据图片画出那些线条吗？

Answer 1

像这样？

为了获得更完整的图像，您应该向我们展示您迄今为止所尝试的内容......

\documentclass[tikz, margin=3mm]{standalone}
\usetikzlibrary{patterns, quotes}
\usepackage{siunitx}

\begin{document}
    \begin{tikzpicture}[
every edge quotes/.append style = {%
        font=\footnotesize, anchor=south, sloped}                            
                        ]
\draw[thick,
      pattern=north east lines
      ]
      (0,0) to ["\SI{30}{cm}"] ++ (0,6)
            -- ++ (3,-3)
            -- cycle;
    \end{tikzpicture}
\end{document}
