A dodecagon has 12 angles. 'Do' means two and 'Deca' means ten. That's how i got it.
A dodecagon has 12 angles. The sum of the interior angles is 1800 degrees, and each angle in a regular dodecagon measures 150 degrees. Thus, a dodecagon not only has 12 angles, but also a specific angle measurement when it is regular.
