    The sum of all the interior angles of a pentagon is:

    A) \[{{180}^{o}}\]                                  

    B) \[{{360}^{o}}\]

    C) \[{{540}^{o}}\]                        

    D)        \[{{720}^{o}}\]

    Correct Answer: C

    Solution :

     Here\[n=5\] Sum of interior angles             \[=(n-2)\times {{180}^{o}}\]             \[=(5-2)\times {{180}^{o}}\]             \[=3\times {{180}^{o}}={{540}^{o}}\]
