Pitagora I² = C1² + C2²
AC² = AB² + BC²
676 = AB² + 100
AB = √576
AB = 24 cm
P = 2·AB + 2·BC
P = 48 + 20
P = 68 cm
AC² = AB² + BC²
676 = AB² + 100
AB = √576
AB = 24 cm
P = 2·AB + 2·BC
P = 48 + 20
P = 68 cm
AB^2 =AC^2-BC^2
AB^2 =26^2-10^2 =676-100 =576
AB =24 cm ; P =2AB+2BC =2*24+2*10 =48+20 =68 cm
