# rename theorem environment to proposition

How can I rename the theorem environment to proposition? In other words, I would like to print:

Proposition 1 instead of Theorem 1/Lemma 1, etc

PS: I am using koma-script article

• Do you want to maintain your current code (which probably uses \begin{theorem} ... \end{theorem}), or create a new environment that prints Proposition instead of Theorem? Are you using any theorem-related packages?

• I would like to create a new environment that prints Proposition. I am using amsmath package Nov 28, 2015 at 7:11
• For future reference, this is information you should typically supply to the community as part of the question.

• @Yorgos -- amsmath has nothing to do with theorems. amsthm is the relevant package. Nov 28, 2015 at 21:20

\newtheorem{prop}{Proposition}

\begin{prop}
