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.

What is the sum of the interior angles of a polygon is 2800 and what type of polygon is it?
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.
What type of regular polygon has equal interior and exterior angles?
A quadrilateral.
What is the sum of interior angles of a icosagon?
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.
How do you work out the angles in a 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.
What type of polygon has equal angles but unequal sides?
quadrate rectangle
What is the sum of the interior angles of a polygon is 2340 What type of polygon is it?
It is a 15 sided polygon
What type of polygon must you have to find out the sum of interior angles?
any polygon
What is the sum of the measures of the interior angle in polygon?
It depends on what type of polygon it is and how many angles it has.
What is the sum of the interior angles of a polygon is 2800 and what type of polygon is it?
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.
What type of regular polygon has equal interior and exterior angles?
A quadrilateral.
What type of polygon has its sum of interior angles to equal 360?
Quadrilaterals.
If the measure of your interior angles is 135 degrees what type of polygon is it?
Hexagon
What type of polygon has interior angles of 720 degrees?
hexagon which has 6 sides
What is the sum of interior angles of a icosagon?
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.
If the polygon is regular what is the size of each interior angle?
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.
In what type of polygon is the sum of the measures of the interior angles equal to 1260?
A nonagon aka enneagon
What type of polygon is it if the sum of the measures of the interior angles is 720 degrees?
It is a 6 sided hexagon
