plz find it i will give u birlent

Answer 1

$\bold{Given \; –} \; ∠PQR = ∠PRQ$

$\bold{To \; Prove\; –} \; ∠PQS = ∠PRT$

$\bold {Solⁿ \; – }$

$∠PQR + ∠PQS = 180° \;\;\;\;\;\;\; -----(i)$

$∠PRQ + ∠PRT = 180° \;\;\;\;\;\;\;-----(ii)$

$From \; (i) \; \& \; (ii),$

$∠PQR + ∠PQS = ∠PRQ + ∠PRT$

$\implies ∠PRQ\!\!\!\!\!\!\!/ \;\;\;+ ∠PQS = ∠PRQ\!\!\!\!\!\!\!/ \;\;\; + ∠PRT \;\;\;\;\;\;\; [∵ ∠PQR = ∠PRQ]$

$\implies ∠PQS = ∠PRT$
