Each interior angle of a regular decagon would measure 144 degrees,
Each angle for a regular nonagon is 140 degrees each.
A regular decagon would have five sets or parallel lines.
If those are exterior angles, the exterior angles of any polygon add up to 360. That would be 18 sides.
The sum of the interior angles of any regular polygon of n sides is equal to 180(n - 2) degrees. Each angle would be 164.35 degrees
A decagon has 10 sides. If it is a regular decagon, all of the sides are the same length. Each side would be 0.8 yards or 2.4 feet in length.
well the total degrees in a decagon is 1440 therefore each interior angle in a regular decagon would measure 144 degrese
Each exterior angle of a regular polygon with n sides is 360/n degrees. So, for a decagon, it would be 360/10 = 36 degrees.
An exterior angle of a regular polygon with n sides is 360/n degrees. So in the case of a decagon that would be 36 degrees. The interior angle is its supplement so 180 - 36 = 144 degrees. Furthermore, a non-regular decagon could have an interior angle with any value in the range (0, 360) degrees. The only constraint is that the sum of all ten interior angles is 1440 degrees.
The measure of an exterior angle of an equiangular pentagon is 72 degrees. An equiangular pentagon is a regular pentagon that has five equal sides and five equal angles. An interior angle of a pentagon is equal to 108 degrees.
It would require 36 degrees.
Each angle for a regular nonagon is 140 degrees each.
For any polygon, whether it is regular or irregular (even concave), the sum of the exterior angles is always 360 degrees. -- WRONG, the answer is 1440 degrees. The sum is equal to (number of sides-2)*180, I believe.
The answer could depend on what you mean by a decalon. The interior angle of a regular decagon is 144 degrees. If two of these met at a point they would cover 288 degrees - leaving a gap in the 360 degrees around a point. If three of them met at a point they would cover 432 degrees - causing an overlap of 72 degrees.
Either could have a larger interior angle. If they were regular, then the interior angle of a triangle would be 60 degrees whereas that of a heptagon would be 128.57 degrees. The REGULAR heptagon would have a larger interior angle than a REGULAR triangle.
The minimum angle of a regular polygon would be 60 degrees.
A regular hexagon's angle would be 120 degrees making the total degrees 720. If it's the degrees of one angle of an irregular hexagon there would be quite a range
The only regular polygon with an interior angle of 90 degrees is the square, which has four sides. Other polygons can have an interior angle of 90 degrees, but they would not be regular polygons.
