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

In triangles DEF and PQR,
∠D = ∠Q and ∠E = ∠R

Concept used :
AAA Similarity Criterion – If in two triangles, all three angles are equal, the triangles are similar.

Formula used:
For similar triangles, the ratio of corresponding sides is equal. Based on the correspondence $$\triangle DEF \sim \triangle QRP.$$​​

​$$\frac{DE}{QR} = \frac{EF}{RP} = \frac{DF}{QP}$$​​
Note that  QP is the same side as PQ, and RP  is the same as  PR. So the correct proportionalities are:
​$$\frac{DE}{QR} = \frac{EF}{PR} = \frac{DF}{PQ}$$​​
​Solution:

(A) $$\; \frac{EF}{PR} = \frac{DF}{PQ}$$​This is true as per the correct ratios

(B) $$\; \frac{DE}{PQ} = \frac{EF}{RP}$$ This is not true because DE corresponds to QR and PQ corresponds to DF

(C) $$\; \frac{DE}{QR} = \frac{DF}{PQ}$$​ (This is true as per the correct ratios, since DF/PQ is the same as DF/QP)

(D)  $$\; \frac{EF}{RP} = \frac{DE}{QR}$$​ (This is true as per the correct ratios)

The statement that is not true is $$\frac{DE}{PQ} = \frac{EF}{RP}.$$
