But how do you know?

i went to a talk at a math conference and the guy proved it
i forget how, but i don't think it was that difficult

If you say the segments creating the vertex have length a, and the base has length b.  Just try writing the statement of each:
   sqrt(a) + sqrt(a) = sqrt(b)
   sqrt(a) + sqrt(b) =  sqrt(a)
It seems you end up with the base equal to zero and 2sqrt(a) = sqrt(b) = 0.
