The sum of the exterior angles of a polygon is 360°
If they are all the same (as the figure is regular) then:
360° = number_of_side × exterior_angle
→ number_of_sides = 360° ÷ exterior_angle
And each is 60°, then
number_of_sides = 360° ÷ 60° = 6
The polygon has 6 sides - it is a hexagon.
360 degrees and the polygon is an equilateral triangle.
1800 degrees
1440 degrees
1440 degrees
Each exterior angle measures 15 degrees
The sum of the measures of the exterior angles of any polygon, regular or irregular, is always 360 degrees. In a regular polygon with ten sides, each exterior angle measures 360 degrees divided by the number of sides, which in this case is 36 degrees. Therefore, the sum of the measures of the exterior angles of a regular decagon is 10 multiplied by 36 degrees, which equals 360 degrees.
360 degrees and the polygon is an equilateral triangle.
1800 degrees
How many sides does a regular polygon have if each exterior angle measures 20?
1440 degrees
1440 degrees
8 and it is called a regular octagon
Each exterior angle measures 15 degrees
Each exterior angle measures 36 degrees
Each exterior angle of a regular 12-gon measures 30 degrees.
540 degrees
The exterior angles of any polygon add up to 360 degrees.
