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(c2 - ((a2 + b2 - c2) / 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!!!
