If `DeltaABC ~ DeltaDEF` and `AB : PQ = 5 : 7` then write the ratio of `A(DeltaABC) : A(DeltaPQR)`.

In the figure, BC=7 and BD=3 then write the ratio of A(DeltaADC) : A(DeltaABC) .

If DeltaABC~DeltaPQR and AB:PQ=2:3 , then fill in the blanks: (A(DeltaABC))/(A(DeltaPQR))=((AB)^(2))/(square)=(2^(2))/(3^(2))=(square)/(square) (A(DeltaABC))/(A(DeltaPQR))=(AB^(2))/(PQ^(2))=(2^(2))/(3^(2))=4/9

In DeltaABC ,B - D - C and BD = 7, BC = 20, then find the ratio (A(DeltaABD))/(A(DeltaABC))

If DeltaABC ~ DeltaDEF and /_A=45^(@) , /_E=87^(@) , then /_C= …… .

If DeltaABC-DeltaDEF such that AB = 1.2 cm and DE= 1.4 cm, the ratio of the areas of DeltaABC and DeltaDEF is:

If DeltaABC~DeltaDEF , AB=4cm, DE=6,EF=9 cm and FD=12 cm, then find the perimeter of DeltaABC .

In (DeltaABC) , MN||BC and AM:AB=1/3 . Then find the ratio of (ar(DeltaAMN))/(ar(DeltaABC))

DeltaABC~DeltaPQR . If AB : PQ=4: 5 , find A(DeltaABC) : A(DeltaPQR) .

If DeltaABC~DeltaPQR,A(DeltaABC)=80, A (DeltaPQR)=125 , then fill in the blanks: (A(DeltaABC))/(A(Delta………..))=80/125:.(AB)/(PQ)=(square)/(square)
