Providing that it is a regular 20 sided icosagon the each interior angle measures 162 degrees
Each interior angle of a regular 45-gon measures 172 degrees
Each interior angle of a hexagon is 120 degrees and there are 6 of them. That would equal 720 degrees.
Normally 4 sides as in a square or a rectangle
Assuming you are referring to a triangle and are asking for one of the interior angle's measurements, this is the answer.Because it is an equilateral triangle, the measures of the 3 angles are the same. They add up to 180 by the interior angles theorem.Thus, the measure is 60 for each angle.
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.
Providing that it is a regular octagon then each interior angle will measure 135 degrees
The interior angle measurement of an octogon is 1080 degrees. Each angle is 135 degrees.
60 degrees
Each interior angle of a regular 45-gon measures 172 degrees
A polygon with 30 sides has a total interior angle measurement of 5040o, with each interior angle measuring 168o.
Each interior angle of a regular 10 sided decagon measures 144 degrees
Providing it is a regular nonagon: Exterior angle: 40 degrees Interior angle: 140 degrees
Each exterior angle 36 degrees Each interior angle 144 degrees A decagon has 10 sides
The sum of the interior angles of an icosagon is 3240 degrees, each angle of a regular icosagon being 162 degrees. * The formula for the sum of an n-sided polygon is 180 (n-2). 180 x 18 = 3240

No - each different n-gon (pentagon, septagon, nonagon, etc) has a different angle measurement.
