A 13 sided polygon also called a triskaidecagon or tridecaogn has a total 1980 degrees for its interior angles.

A 6 sided polygon is called a Hexagon. The sum of the interior angles or a regular hexagon is 720 degrees.

Improved Answer:-A 6 sided polygon is an hexagon and its 6 interior angles add up to 720 degrees

If all of its interior angles are equal then it is a regular polygon

It has 9 sides and is called a nonagon

It is an hexagon which is a 6 sided polygon with 6 interior angles that add up to 720 degrees.

A polygon with 10 sides is called decagon and the sum of the interior angles is 1440 degrees. (10-2)180=1440

If you mean an 11 sided polygon then its 11 interior angles add up to 1620 degrees

In a polygon there are no such angles.

Quindecagon or pentadecagona 15 sided pollygon is called a Pentadecagon, it has interior angles of 156 degrees each

It is a hexagon.

A twenty-sided polygon is called an "icosagon." If it is a regular icosagon - all its sides and angles are equal - then it's interior angles are all 162 degrees. You can verify this by drawing a line to the center from each angle.. There will be 20 small angles arranged in a circle around the center. These must total 360 degrees. As 360 / 20 = 18, this leaves the other angles of each triangle to add up to 162, because the interior angles of a triangle total 180 degrees.

A regular polygon having an interior angle of 120 degrees will have 6 sides and is called an hexagon.

All vertex angles (also called "interior angles") of a regular polygon have equal measures. If this regular polygon has n sides, then the sum of all the interior angles is 162° times n. The sum of the measures of all the interior angles of any polygon with n sides is (n-2) times 180°. So we have this equation 162n=(n-2)(180) which has solution n=20. So the polygon has 20 sides.

Each angle would be 170.27027 degrees. The total sum of all interior angles is 6300 degrees. This shape is called a triacontakaiheptagon.

A [regular] pentagon.

If each of its interior angles is a measure of 108 degrees then it will have 5 sides and is called a regular pentagon.

A 3-sided polygon is called a "triangle".The angles of a triangle don't equal 180 degrees.They total 180 degrees when they're added.

No.No! It is not possible.Regular polygon:Polygon in which all the sides are equal and all the interior angles are equal is called as a regular polygon.Concave polygon:A polygon that has one or more interior angles greater that 180o is called as a concave polygon.It is not possible to have polygon with all sides equal and greater than 180o.Source: www.icoachmath.com it is possibleA concave polygon had to be irregular.

A polygon with an interior angle exceeding 180 degrees is called CONCAVE or RENTRANT.

Yes, but more preferably called consecutive interior angles.

A polygon with five angles and five sides is a pentagon.

an equilateral triangle, or equiangular triangle
