# In $\Delta ABC$ and $\Delta PQR, \angle B, \Delta ABC,$ and $\Delta PQR, \angle B = \angle Q, \angle R=\angle C$ and $AB=\angle Q,\angle R= \angle C$ and $AB =2QR$.Then,thetrianglesare
$\begin{array}{1 1} \text{neither congruent nor similar} \\ \text{congruent as well as similar} \\ \text{congruent but not similar.} \\ \text{similar but not congruent.} \end{array}$
