Question

In ΔDEF and ΔPQR, it is given that ∠D = ∠Q and ∠R = ∠E, then which of the following is not true?

पर्याय

• `(EF)/(PR) = (DF)/(PQ)`

• `(DE)/(PQ) = (EF)/(RP)`

• `(DE)/(QR) = (DF)/(PQ)`

• `(EF)/(RP) = (DE)/(QR)`

Answer 1

`bb((DE)/(PQ) = (EF)/(RP))`

Explanation:

∠D = ∠Q, ∠E = ∠R and ∠F = ∠P.

∴ ΔDEF ∼ ΔQRP ⇒ `(DE)/(QR) = (DF)/(PQ) = (EF)/(RP)`.

∴ `(DE)/(PQ) = (EF)/(RP)` is not true.
