Each interior angle of a regular 12 sided dodecagon measures 150 degrees
The measure of each interior angle of a dodecagon, which is a 12 sided regular polygon, is 150o. This is found in any polygon by multiplying 2 less than the number of sides by 180o and then dividing the product by the number of sides. A dodecagon interior angle is then 10 x 180o/12 = 150o.
The sum of the interior angles of a dodecagon is:sum = (12 - 2) x 180o= 1800oIn a regular dodecagon, each of the interior angles is 1800o ÷ 12 = 150o
It is: 360/12 = 30 degrees
The measure of each interior angle of a fifteen sided regular polygon, a pendedecagon, is 156o.
