What do the angles inside a dodecagon add up to?

144° is the measure of all the ten sides of a decagon. Multiply that number by 10, and you get 1,440° as your final answer. Hope I helped!

No, you did not help! While the answer is correct, it is about a decagon whereas the question was about a dodecagon. The interior angles of a dodecagon sum to (12-2)*180 = 1800 degrees.
