Question

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

Professor PC Thomas Classes · Answer

(d) : Given, in triangles\ $	riangle D E F$ and $	riangle P Q R$ $$ \begin{aligned} & \angle D=\angle Q \ & \angle R=\angle E \ & 	riangle D E F \sim 	riangle Q R P \end{aligned} $$ $	herefore \quad \frac{D E}{Q R}=\frac{E F}{R P}=\frac{D F}{Q P}$\ (If triangles are similar then corresponding sides are proportional)\ Hence, option (d) is not true.\
