A dodecagon
Interior Angle: 150 degrees (Interior Angle Sum: 1800) Exterior Angle: 30 degrees (Exterior Angle Sum: 360)
The interior angles of a 12 sided dodecagon add up to 1800 degrees
The interior angle of a dodecagon is not 1260 that is of a nonagon * * * * * The interior angle of a dodecagon can have any value in the range (0, 360). The only restriction is that the sum of all 12 interior angles (which need not be equal) is 1800 degrees.
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
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 interior angles of a dodecagon sum to 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.
The interior angles of a dodecagon sum to 1800 degrees.
The interior angles of a dodecagon sum to 1800 degrees.
The interior angles of a dodecagon sum to 1800 degrees.
Sum of interior angles of a polygon = (Number of sides - 2)*180 degrees. So, for a polygon, (12 - 2)*180 = 10*180 = 1800 degrees.
