  1. Draw a circle.
  2. Draw a square box.
  3. Select snap to shapes.
  4. With the straight line tool, start a line approximately in the centre of the circle and extend it to the require box corner - this will 'snap'.
  5. Release the line.
  6. Click on the start of the line and move it about until it 'snaps' on the centre.
  7. Release the line.

P.S. Changing the centre to a tangent is much more challenging.
