  • In Delta ABC and Delta DEF is (AB)/(DE) = (BC)/(DF) then they will be similar if:

    A
    `/_ B` and `/_E`
    B
    `/_ A` and `/_D`

    `/_ B` and `/_D`
    D
    `/_ A` and `/_F`

  • Delta ABC has sides of length 5 cm, 6 cm and 7 cm. The perimeter of Delta DEF is 360 cm. If Delta ABC ~= Delta DEF then the ratio of the ratio of the perimeters of Delta ABC and Delta DEF is :

    `1 : 2`
    B
    `2 : 1`
    C
    `1 : 20`
    D
    `20 : 1`
