Question

In given figure the measure of $\angle A+\angle B+\angle C+\angle D+\angle E+\angle F$ is ?

• A. ${120}^o$
• B. ${720}^o$
• C. ${360}^o$
• D. ${540}^o$

Answer 1

Answer: (C)

${360}^o$

$\angle A+\angle C+\angle E={180}^{\circ }....\left(i\right)$
$\angle B+\angle D+\angle F={180}^{\circ }....\left(ii\right)$
On adding (i) and (ii),
$\angle A+\angle B+\angle C+\angle D+\angle E+\angle F={360}^{\circ }$
Hence, option $\left(3\right)$ is correct.
