360/20 ie 18 degrees, assuming regularity.
An exterior angle of a polygon is the supplement of the corresponding interior angle. The exterior angle is the angle between an extended sides of the polygon and the next side of the polygon.
Each interior angle is 165 degrees Each exterior angle is 15 degrees
The exterior angle of any polygon, including a tricontakaitrigon, is the angle formed between one side of the polygon and the extension of an adjacent side. The measure of the exterior angle of a regular tricontakaitrigon is 2 degrees, as each interior angle of this polygon measures 178 degrees.
An exterior angle of the polygon.
The sum of the exterior angles of any polygon is always 360 degrees because each exterior angle is formed by extending one side of the polygon and measuring the angle between that side and the adjacent side. As you move around the polygon, each exterior angle corresponds to a turn made at each vertex. Completing a full turn around the polygon involves turning a total of 360 degrees, regardless of the number of sides. Thus, the sum of all exterior angles is consistently 360 degrees.
It is called an exterior angle.
Exterior Angle.............^_^
Angles outside a polygon, often referred to as exterior angles, are formed when a side of the polygon is extended. These angles are created between the extended side and the adjacent side of the polygon. The sum of the exterior angles of any polygon, regardless of the number of sides, is always 360 degrees. Each exterior angle can be calculated by subtracting the interior angle from 180 degrees.
exterior angle
exterior angle = 360 divided by the number of sidese = 360/s40 = 360/smultiply each side by s40s = 360divide each side by 40s = 99 sides
An interior or exterior angle of the polygon.
Exterior angles are the angles formed when a side of a polygon is extended, and they are adjacent to the interior angle at that vertex. In a polygon with n sides, there are n exterior angles, one at each vertex. The sum of the exterior angles of any polygon is always 360 degrees.
