To find the angle measure of a dodecagon you use the formula n-2 (180) / n with n being the number of sides. A dodecagon has 12 sides. So you do 12-2 (180) /2. That equals 10 (180) = 1800 / 12. That equals 150 degrees.

(n - 2) * 180 is the formula for that. n = number of sides. So dodecagon = 12 sides
12 - 2 = 10
10 * 180
1800
