How many sides and angles does a decagon have?
A decagon has 10 sides, and 10 angles. The sum of the interior angles of a decagon is (10-2)×180° = 1440° In a regular decagon all the angles are congruent at 1440° ÷ 10 = 144°
What is a ten sided geometrical figure called?
A decagon - if the sides are all equal, and the angles are all equal, it is a regular decagon.
What is the size of an exterior angle of 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.
What is the measure of an exterior angle of a twelve sided polygon?
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.
What is the sum of the exterior angle measures of a regular decagon?
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.
What is the measure of one exterior angle of a regular decagon?
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
Measures of a decagon?
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.
How many sides and angles does a decagon have?
A decagon has 10 sides, and 10 angles. The sum of the interior angles of a decagon is (10-2)×180° = 1440° In a regular decagon all the angles are congruent at 1440° ÷ 10 = 144°
What is the measure of one the interior angles of the regular 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
How do you make a decagon?
''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°
What is the size of an exterior angle of 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.
What is a ten sided geometrical figure called?
A decagon - if the sides are all equal, and the angles are all equal, it is a regular decagon.
What is the sum of all the exterior angles in a 6 side regular polygon?
The sum of the exterior angles of any regular polygon is 360°
Shape ten sides?
The shape is called a decagon. If all the sides and angles are the same, it is called a regular decagon.
What is a shape whith 10 sides?
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 is the exterior angle of a hexagon?
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.
How many sides does a not regular decagon have?
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.
