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.
