The sum of the interior angles is 1440 degrees.
There are 1440 degrees in a decagon.
Find any straight side of the decagon. Move along it until it joins another side. That is where an angle is. An angle of a decagon can have any measure between 0 and 360 degrees (except 180 degrees).
Each interior angle of a regular decagon is 144 degrees
360/10 = 36 degrees
The sum of the degrees of any regular polygon with number of sides n is equal to (n - 2) x 180. Therefore, the sum of the internal angles in a decagon is equal to (10 - 2) x 180 = 1440 degrees.
1440 degrees
A decagon has 10 sides, and the whole polygon has 360 degrees, so each angle is 36 degrees.
A decagon will always have its interior angles measure 1480
A decagon has 10 sides, so it also has 10 angles. Each angle of a decagon is 36 degrees (360 degrees divided by 10). Therefore, a decagon has 10 angles of rotation symmetry.
1440
A decagon is a 10 sided polygon. Exterior degrees total 360 Interior degrees total 1440
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.
