What is the sum of the angle measures in dodecagon

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.
