Which among the following statements are not correct for the given triangle PQR?

In a triangle, angle opposite to the longest side is largest and angle opposite to the shortest side is the smallest. 

So, in triangle PQR, QR is the longest side. Hence $\angle P$ is the largest angle. 

Similarly, QP is the shortest side. Hence $\angle R$ is the smallest angle. 

Therefore, $\angle P>\angle Q>\angle R.$ 

Hence, among the given options '$\angle P$ is the smallest angle' is not correct for the given triangle PQR.
