If you don't see the handles for example on square this means the handles are aligned with the main Bezier point. To drag the handles out of the point hold Ctrl and then drag the point. To drag symmetrical handles hold down Shift when dragging the handles.
Hold Ctrl and drag point to reveal the handles.
Hold down Shift and drag the handle to make the point symmetrical.

Open and Closed path
The Path or Polynome can be open or closed. When you draw any of the basic shapes the path is closed. Closed path means the object is filled, where open path shows only outline. If you click on the open path object you will see the Line Width slider appear on the upper toolbar. You can apply any effects,colors or textures on open path as well as on closed. To change the width of the outlined path adjust the Line Width Slider (On the top toolbar)

Note: Click on any point and look at the status bar at the bottom of the screen. You should see something like; Path Point 2. The break point is always at the point 0 and the last point. Also when you select an object with Selection tool you will see a small square at a place where is the point 0 (or start of the path)
