1. ## A Real Math Puzzle - No Kidding.

Can you prove that the OrthoCenter, the CircumCenter and the Cetroid of a triangle are collinear? A spreadsheet is attached that could be useful in solving the problem.

Yes...... <img src=/S/evilgrin.gif border=0 alt=evilgrin width=15 height=15>

Seriously, I think we may have to look up Euler Line

and The Euler Line and the 9-Point Circle

This is much easier that writing out the proof on Woodys <img src=/S/grin.gif border=0 alt=grin width=15 height=15>

If interested, a new sheet with a simple to understand solution is attached...

The Euler (pronounced Oiler) sites are a bit on the complicated side and difficult for anyone but an engineer to understand. <img src=/S/smile.gif border=0 alt=smile width=15 height=15>
