Given a square with the length of one side is 8 cm and a isosceles triangle with the length of its base is 12 cm. If the area of the square is equal to the area of the isosceles triangle then what is the length of the height of the isosceles triangle, in cm?
The right triangle FGH has mid-segments of length 10 cm, 24cm and 26cm. What is the area of triangle FGH
The right triangle FGH has mid-segments of length 10cm, 24cm and 26cm. What is the area of triangle FGH?
Dễ lắm ak nha!
Giả sử FG = 10 cm ; GH = 24 cm ; FH = 26 cm
Ta có: FG2 + GH2 = 102 + 242 = 676 cm2
FH2 = 262 = 676 cm2
=> FG2 + GH2 = FH2 ( vì 676 = 676)
=> Tam giác FGH vuông tại G
=> \(S_{FGH}\) = 10 x 24 = 240 (cm2)
Vậy ......................

À đáp án là 480 cm mới đúng nha .
Mid-segments là đường trung bình mà .
Vì đường trung bình của tam giác lần lượt là 10cm ; 24cm ; 26cm =)) Các canh của tam giác lần lượt là 20cm ; 48cm ; 52cm
Ta thấy : 52^2 = 48^2 + 20^2
Nên tam giác FGH là tâm giác vuông
Diện tích tam giác FGH là :
(20*48):2=480(cm2)
