Yuzaga doir masalalarni yechish

Shakl yuzlari : • To’g’ri to’rtburchak yuzi • Parallelogramm ; • Trapetsiya ; • Romb ; • To’g’ri burchakli uchburchak ; • Ixtiyoriy uchburchak • Kvadart • S =a*b • S = a*h • S = (a+b)/2 *h • S = 1/2d1*d2 • S =1/2 a*b • S = 1/2a*h • S = a*a

Formulalar eslab qoling! • Kvadrat perimetri • To’g’ri to’rtburchak perimetri ; Pifagor teoremasi ; • P= 4a P = 2(a+b) c 2 =a 2 +b 2 b 2 =c 2 - a 2
