Question

If in two triangles DEF and PQR, ∠D = ∠Q and ∠R = ∠E, then which of the following is not true?

Answer 1

Given  : Two triangles DEF and PQR, ∠D = ∠Q and ∠R = ∠E,

To Find : which of the following is not true?

Solution:

ΔDEF  and Δ PQR

∠D  = ∠ Q

∠E =  ∠R

=> ∠F  = ∠P

=> ΔDEF ≈  ΔQRP

=> DE/ QR  = EF/ RP   = DF / QP

option 1 : EF/PR = DF/PQ          PR = RP  & QP = PQ

Hence Correct

option 2:  DE/QR = EF/RP  Correct

option 3  : DE/QR  = DF/PQ      PQ = QP

Hence Correct

Option 4   EF/RP  = DE/QR   Correct

All options are correct

if option b is   DE/PQ = EF/RP then it  is not true
