Have you ever wondered whether geometry and trigonometry help can be done over the Internet?  Well, it can.  I can set up a time with your math student to chat and draw diagrams using this whiteboard.  The password is fibonacci.  Try it now to see its capabilities and become familiar with it.  I don't monitor the whiteboard, so you'll need to send me an email suggesting a time that we might both use the whiteboard.  Don't forget to tell me what time zone you're in.  To get started, if there is a diagram you want to show me, you can write it up on the whiteboard and save it, with a title and your name.  Then I can add to it, and save it with the same title so you can find it.
