Dodecagon is a plane figure with 12 sides. To find the sum of angles of a dodecagon, we have to use the formula of sum of angles of a polygon with n sides, which is
S= (n-2)180
For Dodecagon , n=12. Therefore on substituting 12 for n , we will get
S= (12-2)180 =10*180 = 1800 degree .
SO the sum of angle measures of a dodecagon is 1800 degree .
