I am trying to draw a square with the four points A, B, C, and D labeled along with functions listed by each "arrow." I based my code on the triangle that was on the tikz example. Something is obviously wrong.

Heck I'd just be happy to get the square to show.

Code:

```
\begin{tikzpicture}[blue]
\coordinate (A) at (0,0);
\coordinate (B) at (4,0);
\coordinate (D) at (4,4);
\coordinate (C) at (0,4);
\draw[blue, ultra thick] (A) -- (B) -- (D) -- (C) cycle;
\path (A) node[below left] {A} -- (B) node[below right] {B} -- (D) node[above right] {D} -- (C) node[above left];
\path (A) -- node[below] {f} (B) -- node[right] {$\beta$} (D) -- node[above left] {g} (C) -- node[left] {$\alpha$} (A);
\end{tikzpicture}
```

Would someone please guide me through this one? And how would you make the lines arrows?

Thanks!
