I'd like the arrange these figures so there are two figures next to each other and one below, like an upside down triangle, so that they all fit on one page and are a reasonable size. How do I do this?
\begin{figure}[H]
\centering
\begin{subfigure}[H]{0.75\textwidth}
\centering
\includegraphics[width=0.75\linewidth]{dragratio}
\caption{}
\label{fig:dragratio}
\end{subfigure}
\begin{subfigure}[H]{0.75\textwidth}
\centering
\includegraphics[width=0.75\linewidth]{dragratio2}
\caption{}
\label{fig:dragratio2}
\end{subfigure}
\begin{subfigure}[H]{0.75\textwidth}
\centering
\includegraphics[width=0.75\linewidth]{dragratio3}
\caption{}
\label{fig:dragratio3}
\end{subfigure}

\caption{(a) Numerical solutions for the constant-curvature body, $F(x)=x(1-x), x \in (0,1)$, at small times. This figure shows the drag force $D$ versus the scaled mass $M$ for various values of the ratio between the inertia $I$ and the mass $M$, i.e. for various values of $R=\frac{I}{M}$. Here $g=10$ and $A=0.7$. (b) As for (a) but with $A=0.5$. (c) As for (a) and (b) but with $A=0.25$.}
\end{figure}
(a)
,(b)
, and(c)
, and do you need to be able to\ref
the subfigures or only need to\ref
the complete figure?
