a triangle has 180 degrees total so whoever told you that is dumb maybe your thinking of a square but in that case you'd still have one more 90% angle
If you draw a triangle on a globe you can accomplish a triangle with 3 90 degree angles, have a look on Metacafe and type in "270 degree triangle, yes 3 right angles". You can watch this for your self.
