The exterior sum of angles for any polygon is always 360 degrees.The sum of the exterior angles of a 12 sided dodecagon is 360 degrees
The exterior angles of a 12 sided dodecagon add up to 360 degrees
Exterior angles: 360 degrees Interior angles: 1800 degrees
Sum of exterior angles of an n-gon is 360 degrees. A dodecagon has 12 exterior angles which are all equal and so each is 360/12 = 30 degrees.
It depends on what the measures relate to: lengths of sides, interior angles, exterior angles, ...
A dodecagon has 12 interior angles that add up to 1800 degrees.
The interior angles of a dodecagon sum to 1800 degrees.
The 12 interior angles of a dodecagon add up to 1800 degrees
For any given polygon, the exterior angles will sum to 360 degrees. Thus, for a regular polygon, dividing by the number of exterior angles (the same as the number of sides) will produce the exterior angle. For a dodecagon (12 sides), 360/12=30 degrees. You can also find the interior angle easily because the interior and exterior angles are supplementary: 180-30=150 degrees for an interior angle.
No: The sum of the exterior angles of a polygon is 360o. For a dodecagon (12 sides) the exterior angle is 360o / 12 = 30o. The interior and exterior angles are supplementary and so they sum to 180o; thus the interior angle of a dodecagon is 180o - 30o = 150o. For an interior angle of 144o, the exterior angle is 180o - 144o = 36o, so there are 360o / 36o = 10 sides (a decagon).
The sum of the exterior angles of a polygon is 360o.
The interior angles of a dodecagon sum to 1800 degrees.
