角度ラベルの移動

【有識者求】tikzのanglesライブラリで，ラベルの位置をもう少し回転させてずらすオプションってあったりしますか…？ pic.twitter.com/ZCeDuZ8gNo

ラベルには中かっこ（{…}）でオプションを追加できます。

\documentclass[tikz,border=10pt]{standalone}
\usetikzlibrary{angles,quotes}
\begin{document}
\begin{tikzpicture}[every node/.style = {font = \scriptsize}]
  % Axes
  \draw[-stealth] (-1.2,0) -- (2.2,0) node[right] {$x$};
  \draw[-stealth] (0,-1.2) -- (0,1.5) node[above] {$y$};
  % Circle
  \draw circle(1);
  % Labels
  \node at (1.1,0) [below] {1};
  \node at (0.2,1.15)      {1};
  \node at (2,0) [below]   {2};
  \node at (0.2,0) [below] {0};
  % Line from origin to (2,1)
  \draw (-1.2,-0.6) -- (2,1);
  % Dashed projection lines
  \draw[dashed] (2,1) -- (2,0);
  \draw[dashed] (2,1) -- (0,1);
  \coordinate (0) at       (0,0);
  \coordinate (A) at     (0.2,0);
  \coordinate (B) at (-0.2,-0.1);
  % Angle arc with label
  \pic[draw, -stealth, "$\theta$"{shift = (20:-0.20)},
    angle radius = 8, angle eccentricity = 1.3]
    {angle = A--0--B};
\end{tikzpicture}
\end{document}
