Yes, you can derive Heron's Formula for by choosing a vertex, dropping a
perpendicular, and eliminating variables. The funny thing is that Heron's
Formula is symmetrical in the variables a,b, and c....so why do you have to
use a proof that's so UN-symmetrical?

It's a good problem to look for a symmetrical derivation of Heron's
Formula...one that doesn't start by choosing a particular side as the
"base". I know of two such methods.
