The sum of the interior angles of any regular polygon of n sides is equal to 180(n - 2) degrees.
1440 degrees

The exterior angles of any polygon add up to 360 degrees including a 10 sided regular decagon of which each exterior angle will measure 360/10 = 36 degrees.
Any angle that you like. There are no constraints on a single angle of a decagon, only on their sum.
Marcus is correct. The sum of the exterior angles of any polygon is always 360 degrees. A decagon has 10 sides, so each exterior angle measures 36 degrees (360 degrees divided by 10). A heptagon has 7 sides, so each exterior angle measures 51.43 degrees (360 degrees divided by 7). Therefore, the sum of the exterior angles of a decagon is indeed greater than that of a heptagon.
Interior angles add up to 1440 degrees Each interior angle of a regular decagon measures 144 degrees
The sum of the measures of the interior angles of a polygon can be calculated using the formula ( (n - 2) \times 180^\circ ), where ( n ) is the number of sides. For a decagon, which has 10 sides, the calculation is ( (10 - 2) \times 180^\circ = 8 \times 180^\circ = 1440^\circ ). Thus, the sum of the measures of the interior angles of a decagon is 1440 degrees.

Each exterior angle measures 36 degrees and the 10 exterior angles add up to 360 degrees.

The exterior angles of any polygon add up to 360 degrees including a 10 sided regular decagon of which each exterior angle will measure 360/10 = 36 degrees.
The sum of the exterior angles in any polygon is 360 degrees.Therefore that polygon is a decagon.
Each interior angle of a regular 10 sided decagon measures 144 degrees
A dicotogon, also known as a 10-gon or decagon, has ten angles. Each interior angle of a regular decagon measures 144 degrees, while the sum of all interior angles in a decagon is 1,440 degrees.
Add each side of the decagon, or all ten sides, to get the sum.
1440 degrees
