# A particular big Delta

I would like to insert the below mathematical symbol, it looks like a big Delta but different. Is there command to obtain a similar shape?

• It seems to be a big delta in italics. Have you tried detexify? – TeXnician May 10 '17 at 8:07
• @TeXnician, after your comment, I tried it but it only gives variants of the ordinary big Delta which are all like equilateral triangles. But the above image look likes very near to a right triangle (but not exactly). The below solution of c.p. is very near. – Name May 10 '17 at 8:34

It is the following Greek character: \varDelta. It requieres amsmath.

• Thank this is very near, however I have the impression that the right side of the triangle in the image is more upright. Hence let me wait a little bit for possible alternative solutions before accepting your answer. – Name May 10 '17 at 8:27
• Sure. The angles could be font-dependent as well. – c.p. May 10 '17 at 8:28

Pick your own desired slant, using Bruno's \slantbox, given at Shear transform a "box" (pdflatex only)

\documentclass{article}
\usepackage{amsmath}
\newsavebox\foobox
\newcommand{\slantbox}[2][.5]{\mbox{%
\sbox{\foobox}{#2}%
\hskip\wd\foobox
\pdfsave
\pdfsetmatrix{1 0 #1 1}%
\llap{\usebox{\foobox}}%
\pdfrestore
}}
\begin{document}
$\Delta \varDelta$ versus $\slantbox[.4]{$\Delta$} \slantbox[.45]{$\Delta$} \slantbox[.5]{$\Delta$} \slantbox[.55]{$\Delta$} \slantbox[.6]{$\Delta$}$
\end{document}
