From: Denis Borris

came across an old geometry set the other day; started fooling around, to see what I could remember from High School....

worked out the height of a triangle ABC to be:
(promise not to laugh!)
sqrt(c^{2} - ((a^{2} + b^{2} - c^{2}) / 2a)^{2})
(also works by switching the b and c)

A c b B D C a

(gives me length of AD)

then I tried to simplify this and couldn't; did all kinds of "searches" (one took me to your page) and couldn't find anything on "height of a triangle"; is there a "standard formula" that gives the height given a b c ?

thanks for your help.

That was from Denis Borris. we don't have "bad days"; Ottawa, Ontario, Canada. but "bad days" have us!!! Be not shy: borrisd@magi.com
