WebEuler s birth) we use proofs without words to prove three simple lemmas that can be combined with the arithmetic mean-geometric mean inequality in order to prove Euler s triangle inequality with only simple algebra (and without reference to the the-orem above). The proof is derived from one that appears in [ 3]. Coxeter [ 1] notes that WebThese pdf files are furnished by JSTOR. Classroom Capsules would not be possible without the contribution of JSTOR.

Therefore c 2= 4 ab 2 +(b-a)2 = 2ab+b2-2ab+a2 = a2 +b, namely c2 = a 2+b.
