  • diket : ABC sebangun ∆PQR
    BC = 4 cm
    AC = 5 cm
    PQ = 12 cm
    QR = 8 cm
    tanya panjang PR ?

    AB ~ PQ
    BC ~ QR
    AC ~ PR

    jawab
    AB/PQ = BC/QR = AC/QR
    AB/12 = 4/8 = 5/PR
    PR = 5/PR = 4/8
    PR = 5 × 8/4
    PR = 40/4
    PR = 10 cm
    jadi, panjang PR = 10 cm
    maaf klo slh
