<p>This was written to be used a “teacher-led” resource. It was written using the enhanced features of PowerPoint 2003; therefore the full effect of the lesson can only be seen using PowerPoint 2003 (or PowerPoint XP). If you are running Office 2000; you can download a PowerPoint 2003 Viewer from Microsoft and this will enable you to run the file as it was intended. In response to the feedback I’ve received; I have removed the security on the original file to enable it to be saved to an external source (flash drive; etc).</p>

This is lovely!
This is lovely and effective - this is what math is about at this level!
I love to be able to see why, as do my students. So thanks for this. A natural extension would be to look for angles greater than 45.
visually very nice and convincing for angles of theta less than 45 degrees
