There is a square sign in the end of proof environment. I proved something outside of proof environment. Because I had to have 'Proof of Theorem 3', I need to put a square as the same size as proof square. this \square is too small. any solution?

  • I am guessing \Box. If this does not fit, give a MWE. – Denis Oct 06 '20 at 05:59

    Your question does not make much sense without code others can copy and try as is – daleif Oct 06 '20 at 06:16

    If you are using amsthm then \qed to make a box flush right, or \qedsymbol just to make the box on its own. – David Carlisle Oct 06 '20 at 06:42

    You can simply do \begin{proof}[Proof of Theorem~\ref{label}] followed by \end{proof} at the end. Here label stands for the actual label you used in the said theorem. – egreg Oct 06 '20 at 12:13

If you are using amsthm.sty then its simple as suggested by egreg and the usage is:

\documentclass{book}
\usepackage{amsthm}

\begin{document}


\begin{proof}[Proof of ...]
....
\end{proof}
\end{document}

As you are not providing any MWE I assumed that you are using standard LaTeX class file...
