Question 1191965
<pre>
The sum S of the interior angles of a n-sided polygon is

{{{S}}}{{{""=""}}}{{{(n-2)*180^o}}}

Since it's a hexagon, n=6, so

{{{S}}}{{{""=""}}}{{{(6-2)*180^o}}}
{{{S}}}{{{""=""}}}{{{4*180^o}}}
{{{S}}}{{{""=""}}}{{{720^o}}}

Since the hexagon is regular, all the interior angles
are congruent (I say "equal", since I'm from the old
school).

So we divide by 6 to get the answer.

Answer: {{{720^o/6^""}}} which is {{{120^o}}}
