I have this one student who reads a lot and knows lots of big, fancy words. Then he tries to use them in math class. And when he's asked to prove indirectly that neither base angle of an isosceles triangle can be a right angle, this is what he answers:
Let one assume that in an isosceles triangle, either one of the base angles is in good possibility an angle amounting to 90 degrees. In an isosceles triangle, the base angle are always by definition congruent, so both ammount to 90 degrees each, a 180 degree total with the third angle not surmounting in excellence or degradation beyond 0 degrees. This is most innacurate, as no triangle may posess an angle whose measure is 0 degrees nor is a triangle classified as such according to it's definition have only two sides. Therefore, in an isosceles triangle neither base angles may attain the ninety degrees of an right triangle.
In comparison, this is what a classmate wrote:
If an triangle is a isosceles then the base can be a right triangle a triangle is not a isosceles neither base angles can be a right angle.
