\begin{definition}[right-angled triangles] \label{def:tri} | ||
A \emph{right-angled triangle} is a triangle whose sides of length~\(a\), \(b\) and~\(c\), in some permutation of order, satisfies \(a^2+b^2=c^2\). | ||
\end{definition} | ||
\begin{lemma} | ||
The triangle with sides of length~\(3\), \(4\) and~\(5\) is right-angled. | ||
\end{lemma} | ||
\begin{proof} | ||
This lemma follows from \cref{def:tri} since \(3^2+4^2=9+16=25=5^2\). | ||
\end{proof} | ||
\begin{theorem}[Pythagorean triplets] \label{thm:py} | ||
Triangles with sides of length \(a=p^2-q^2\), \(b=2pq\) and \(c=p^2+q^2\) are right-angled triangles. | ||
\end{theorem} | ||
\begin{remark} | ||
These are all pretty interesting facts. | ||
\end{remark} | ||
