Blumenstein). Subject: Thanx, here's another... Yup, that's right. Thank you for the overwhelming response to the pentagon problem. Now that you've laid to rest one little demon, could you do me another favor... "The orthocenter of an isosceles triangle lies on the incircle of said triangle. Determine the cosine of the vertex angle." This came off some contest (I think Penn State) in 1983 or 84 and has haunted some friends and I for a while. Help, please? ("The BBC would like to apologize for the next announcement.") Thanx, Michael Rios ihlpg!rioss P.S. Please don't send mail to J. Blumenstein, since I have to clean it all out. Send it to the address above. -- John T. Blumenstein ihuxr!eagle
