## The Nine Point Circle

This demo requires java applet support in your browser. If you don't have it,
you will see nothing below.

We will present 3 proofs of this result, all based on *Circles: a
Mathematical View,* by Dan Pedoe, Dover Publications, 1979.

### Why 3 proofs?

Well, why are there many biographies of Abraham Lincoln? Each proof
illuminates the relationships among the parts of the triangle and various parts
of geometry. That is, each proof gives you a different view of the subject. The
mere statement of a theorem is like a flat statement that Lincoln was the 16th
president. We want to know more than that.
