A decagon is a polygon with 10 sides. In a decagon, each interior angle measures 144 degrees. An acute angle is an angle that measures less than 90 degrees. Since all the interior angles of a decagon are 144 degrees, there are no acute angles in a decagon.
An exterior angle of a decagon can have any value in the range (0, 360) degrees - excluding 180 degrees. The only constraint is that the sum of all exterior angles must be 360 degrees.
A decagon - if the sides are all equal, and the angles are all equal, it is a regular decagon.
If the 12-sided polygon is 'regular', then each of its exterior angles is 30 degrees. Whether the polygon is regular or not, all 12 of its exterior angles still add up to 360 degrees, but they may not all be equal.
It is generally accepted to count only one vertex per side when calculating the sum of exterior angles. If this is what you mean, then for every convex polygon (all angles point away from center), the sum is always 360º.However, you can also count two vertexes per side, so the sum would then be double, or 720º.
36oFor all polygons, the sum of the exterior angles is 360o.For a regular polygon they are all the same thus:exterior_angle = 360o ÷ number_of_sidesSo for a decagon with 10 sides this becomes:exterior_angle = 360o ÷ 10= 36oIt is 36 degrees
The answer depends on what you are trying to measure: interior angles, exterior angles, central angles, lengths of sides, apothems, perimeter, lengths of diagonals, area, etc. And since you have not bothered to share that crucial bit of information, I cannot provide a more useful answer.
A decagon is a polygon with 10 sides. In a decagon, each interior angle measures 144 degrees. An acute angle is an angle that measures less than 90 degrees. Since all the interior angles of a decagon are 144 degrees, there are no acute angles in a decagon.
First of all, a decagon is a polygon with 10 sides. A regular decagon is a decagon in which all of the sides and angles are equal. Since there are 360o in a complete rotation, you can simply divide 360o by 10. 360o / 10 = 36o
''Decagon'' is any polygon with ten sides and ten angles ''Regular decagon'' is a polygon with ten sides of equal length and all angles equal to 144°
An exterior angle of a decagon can have any value in the range (0, 360) degrees - excluding 180 degrees. The only constraint is that the sum of all exterior angles must be 360 degrees.
A decagon - if the sides are all equal, and the angles are all equal, it is a regular decagon.
The sum of the exterior angles of any regular polygon is 360°
The shape is called a decagon. If all the sides and angles are the same, it is called a regular decagon.
You just call it a decagon. If all the angles and sides are equal then it's a regular decagon. If not, it's an irregular decagon.
what are the exterior Angles of a hexagon, heptagon, octagon, decagon and an icosagon ?If all the exterior angles of a hexagon or any polygon equal 360, then just divide by the number of vertices and there's one exterior angle of the polygon.
It still has ten sides, same as a normal decagon. "Irregular" simply means that all the sides and angles of the decagon are not congruent.
