math-modesymbols

Cannot find one, all triangle symbols are equilateral triangles.

Best Answer

If you have access to Unicode fonts there is U+2BBF (⊿) RIGHT TRIANGLE

Otherwise, picture mode to the rescue:

enter image description here

\documentclass{article}

\usepackage{amsmath}
\def\lr{\mbox{\begin{picture}(7,10)
\put(1,0){\line(1,0){5}}
\put(1,0){\line(1,2){5}}
\put(6,0){\line(0,1){10}}
\end{picture}
}}

\def\ll{\mbox{\begin{picture}(7,10)
\put(1,0){\line(1,0){5}}
\put(6,0){\line(-1,2){5}}
\put(1,0){\line(0,1){10}}
\end{picture}
}}
\begin{document}

\begin{align}
 A &= \ll\\
 B &= \lr
\end{align}

\end{document}

[Tex/LaTex] symbol for the y intercept in a linear model

% arara: pdflatex

\documentclass{article}
\usepackage{amssymb}

\begin{document}
    For the y-intercept, a lot of people use the letter $b$, but there is no reference on this. You can refer to your intercept easily as $f(0)$ or name the point $\mathrm{P}(0,f(0))$. A last suggestion would be to type $f(x)\big|_{x = 0}$.

    As always, you do have the possibility to define your own symbols and use them in your whole document:
    \begin{tabbing}
        \hspace*{5ex}\= \kill
        $\mathfrak{y}$ \> $y$-intercept \\
        $\mathfrak{x}$ \> $x$-intercept % just examples, I was surprised by the ugly result...
    \end{tabbing}
\end{document}
