C-06-Q139mediumsingle_mcq

In an equilateral $\triangle PQR$ with $QR$ extended to $S$ , the interior adjacent angle at $R$ is—

a $30°$
b $60°$
c $90°$
d $120°$

ব্যাখ্যা

The interior angle at each vertex of an equilateral triangle is $60°$ , and extending $QR$ to $S$ does not change the interior angle at $R$ , which remains $60°$ .
