Best Answer

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.

The interior angles of a regular polygon must be 60 degrees or greater.

No regular polygon can have an interior angle of 180 degrees or more. No regular polygon can have an interior angle of 180 degrees or more. No regular polygon can have an interior angle of 180 degrees or more. No regular polygon can have an interior angle of 180 degrees or more.

No.

The sum of the interior angles of a n-sided polygon is (n-2)*180 degrees. This is true whether or not the polygon is regular.

The interior angles of a polygon (regular or not) with n sides sum to (n - 2)*180 degrees.

The sum of the interior angles of an n-sided polygon is 180n - 360 degrees.

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

Providing it is a regular polygon they are 156 degrees

A 13 sided regular polygon

The interior angles of a regular polygon cannot be less than 60 degrees so 24 degrees is not possible. ------------------------------- However a regular polygon with EXTERIOR angles of 24° has 360° ÷ 24° = 15 sides.

If it's a regular polygon then each interior angle measures 120 degrees.

No.

No. To elaborate, the smallest regular polygon, an equilateral triangle, has 60 degree interior angles. The next larger one, a square, has 90 degree interior angles. In fact, for any regular polygon, the interior angles measure 180*(n-2)/n degrees, where n is the number of sides. No polygon has less than 3 sides. Thus, no regular polygon can have interior angles less than 60 degrees.

Any polygon can gave an interior angle of 92 degrees. However, no regular polygon can have interior angles of 92 degrees.

That's true if the interior angles are 108 degrees, but a regular polygon cannot have exterior angles of 108 degrees.

If its a regular polygon with each interior angle being 179 degrees then the polygon will have 360 sides.

The interior angles of a 15 sided polygon add up to 2340 degrees and if it is a regular polygon then each interior angle is 156 degrees.

Its 5 interior angles add up to 540 degrees
