title: Explaining DrawArc method?
body: <p>I have a task in which I have to draw a <strong>Figure of Eight</strong>, so I thought of it as drawing four arcs. I tried using the <code>DrawArc</code> method but I really don't understand how does it work at all.</p>
  
  <p>The <code>DrawArc</code> method takes 4 parameters:
  1-The pen.
  2-Rectangle to draw in.
  3-Start angle.
  4-Sweep angle.</p>
  
  <p>What I don't get is the start and sweep angle, could anybody with knowledge tell me what are these 2 parameters and how do they effect the drawing ?</p>
  
  <p>Also does giving the rectangle parameter takes the (0,0) as starting point.</p>
  
  <p>Edit:</p>
  
  <p>I have tried the following code:</p>
  
  <pre><code>        e.Graphics.DrawArc(drawPen, 0, 0, 600, 400, 45, 90);
          e.Graphics.DrawArc(drawPen, 0, 345, 600, 400, -45, -90);
  </code></pre>
  
  <p>which resulted in the following:</p>

  <p>I would like to make it larger, I have played with the code but not success, I didn't understand what I am doing, I was just changing numbers, that is why I asked for an explanation.</p>
