By "external angle" (sorry I'm not native English speaker, so I may be unclear
sometimes ;-)) I meant the angle formed between an edge (or side) and the
extension of an adjacent edge. It's like the gamma angle on the second figure
on http://mathworld.wolfram.com/ExteriorAngle.html

You're right, I meant "Also note that an equilateral triangle is also
_isosceles_" (or at least a particular case of it) :-)
