Interior Angle: 150 degrees (Interior Angle Sum: 1800) Exterior Angle: 30 degrees (Exterior Angle Sum: 360)
Each exterior angle = 360/12 = 30 degrees. Each interior angle = 180 - 30 =150 degrees.
150
360/12 = 30 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 is: 360/12 = 30 degrees
For the 12-sided polygon, each exterior angle is 30 degrees (360/12).
Interior Angle: 150 degrees (Interior Angle Sum: 1800) Exterior Angle: 30 degrees (Exterior Angle Sum: 360)
Each exterior angle = 360/12 = 30 degrees. Each interior angle = 180 - 30 =150 degrees.
Each interior angle measures 150 degrees Each exterior angle measures 30 degrees
150
The largest exterior angle measure is 120o. It is the exterior measure of an equilateral triangle (which is a regular polygon).
360/12 = 30 degrees
It is 150 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.
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.
Each exterior angle will measure 9 degrees
