$2$(a) If $\displaystyle \triangle \mathrm{ABC} \sim \triangle \mathrm{PQR}$ in which $\displaystyle \mathrm{AB}=6 \mathrm{~cm}, \mathrm{BC}=4 \mathrm{~cm}, \mathrm{AC}=8 \mathrm{~cm}$ and $\displaystyle \mathrm{PR}=6 \mathrm{~cm}$, then find the length of ( $\displaystyle \mathrm{PQ}+\mathrm{QR}$ ).

OR

(b) In the given figure, $\displaystyle \frac{\mathrm{QR}}{\mathrm{QS}}=\frac{\mathrm{QT}}{\mathrm{PR}}$ and $\displaystyle \angle 1=\angle 2$, show that $\displaystyle \Delta \mathrm{PQS} \sim \Delta \mathrm{TQR}$. 2025_CBSE_Mathematics_Set_Region1_Subset_Set1_Q24_SECTION-B_b_p8_22
