The sum of angles of a regular polygon:
(n - 2)180 = 3,420
180n - 360 = 3,420 add 360 to both sides;
180n = 3,780 divide both sides by 180;
n = 21
Thus a 21-side regular polygon has the sum of interior angles 3,420 degrees.
If you mean interior angles of 2800 degrees then no such polygon exist because one of its sides woud not meet up with another side.
A quadrilateral.
That will depend on what type of isogon it is because an isogon is the name given to any regular polygon whose interior angles are equal.But in the general: (n-2)*180 = sum of interior of any polygon whereas 'n' is the number of sides of the polygon.
There is no way to work out the angles in a general polygon. The sum of the interior angles of a polygon, with n sides, is (n-2)*pi radians [or (n-2)*180 degrees]. Therefore, if you know the measure of n-1 angles, you can work out the size of the nth angle.Alternatively, if the polygon is one of the rare type - a regular polygon - then all its angles are equal. In that case, you can divided the above sum by n.
A nectagon is a polygon with nine sides and nine angles. It is a type of nonagon, which is a polygon with any number of sides greater than four. The sum of the interior angles of a nectagon is 1260 degrees, calculated using the formula (n-2) x 180, where n represents the number of sides.
It is a 15 sided polygon
any polygon
It depends on what type of polygon it is and how many angles it has.
If you mean interior angles of 2800 degrees then no such polygon exist because one of its sides woud not meet up with another side.
A quadrilateral.
Quadrilaterals.
Hexagon
hexagon which has 6 sides
That will depend on what type of isogon it is because an isogon is the name given to any regular polygon whose interior angles are equal.But in the general: (n-2)*180 = sum of interior of any polygon whereas 'n' is the number of sides of the polygon.
this depends on what type of polygon it is.. if it is a regular triangle, then all interior angles measure up to 180 degrees. So, a triangles interior angles would measure 60 degrees each.
A nonagon aka enneagon
It is a 6 sided hexagon
