\begin{theorem}
Let $f$ be a function whose derivative exists in every point, then $f$ is 
a continuous function.
\end{theorem}
 
\begin{theorem}[Example of theorem title/optional]
\label{pythagorean}
Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.  
\begin{equation}
x^2 + y^2 = z^2
\end{equation}
\end{theorem}

And a consequence of theorem \ref{pythagorean} is the statement in the next 
corollary.
 
\begin{corollary}
There's no right rectangle whose sides measure 3cm, 4cm, and 6cm.
\end{corollary}
 

Unnumbered theorem-like environments are also possible.
 
\begin{remark}
This statement is true, I guess.
\end{remark}
And the next is a somewhat informal definition
 
\theoremstyle{definition}
\begin{definition}{Fibration}
A fibration is a mapping between two topological spaces that has the homotopy lifting property for every space $X$.
\end{definition}

\begin{lemma}
Given two line segments whose lengths are $a$ and $b$ respectively there 
is a real number $r$ such that $b=ra$.
\end{lemma}
 
\begin{pro}
To prove it by contradiction try and assume that the statemenet is false,
proceed from there and at some point you will arrive to a contradiction.
\end{pro}

 
You can reference theorems such as \ref{pythagorean} when a label is assigned.
