What is the sum of the measures of the interior angles of a decagon?
1440
What is the sum of a exterior angle measures of a regular decagon?
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.
What degree angle do you cut your wood to make a decagon?
Any angle that you like. There are no constraints on a single angle of a decagon, only on their sum.
What is the interior angle for a decagon?
Interior angles add up to 1440 degrees Each interior angle of a regular decagon measures 144 degrees
Marcus says that the sum of the exterior angles of a decagon is greater than that of a heptagon because a decagon has more sides. Liam says that the sum of the exterior angles for both polygons is the?
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.
