Question

If in two triangles $	riangle DEF$ and $	riangle PQR$, $\angle D = \angle Q$ and $\angle R = \angle E$, then which of the following is *not* true?

Accepted Answer

Step 1: $\angle D = \angle Q$, $\angle R = \angle E \Rightarrow 	riangle DEF \sim 	riangle QRP$. So $\frac{DE}{QR} = \frac{EF}{RP} = \frac{DF}{QP}$. Option (D) $\frac{DE}{PQ} = \frac{EF}{RP}$ is not true.
