☺ Salut ☺

Le théorème de Pythagore sert à trouver l'hypothénus d'un triangle rectangle, soit la diagonale d'un carré. Le théorème ${AB}^{2} = {BC}^{2} + {AC}^{2}$ .

$\rule{6cm}{1mm}$

• Posons $BC\;et\;AC = 6\;cm$ .

• Calculons $AB$ :

${AB}^{2} = {6cm}^{2} + {6cm}^{2}$

${AB}^{2} = 36{cm}^{2} + 36{cm}^{2}$

${AB}^{2} = 72{cm}^{2}$

$\sqrt{{AB}^{2}} = \sqrt{72{cm}^{2}}$

$\boxed{\green{AB = 8,48cm}}$
