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.
Interior angles add up to 1440 degrees Each interior angle of a regular decagon measures 144 degrees
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.

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

Each interior angle of a regular 10 sided decagon measures 144 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.
Add each side of the decagon, or all ten sides, to get the sum.
1440 degrees
