Re: How to compute triangle base/altitude intersection

Maybe I'm missing something, or my math is rusty, but if you
found C1 and C2 using circles as described above,
then :
BC1==BC2 (both are radii of the same circle centered at B).
BD<BC1

That makes line segment C1C2 perpendicular by definition.

My apologies to Pascal Bourguignon and Richard Heathfield, both of whom I
appear to have corrected incorrectly.

I should have had more faith in myself. :-)

Welcome back :-)

Thanks. My Linux box finally went down after 24/7ing it for a year and a
half. XP won't talk to my router for some reason, so I had to wait for the
hardware chappy to do his magic. It eventually turned out to be a bad
connection of something or other to the motherboard (and the wrong heat
sink on the CPU, and an entire vacuum-cleaner-tank's worth of dust, and...
and...). But Linux is once again firing on all four cylinders. Yay!
