Each interior angle measures 144 degrees
Each interior angle of a regular 10 sided decagon measures 144 degrees
Interior angle: 144 degrees
Divide the 360 by 10
Providing that it is a regular 10 sided decagon then each interior angle is 144 degrees
Each interior angle measures 144 degrees
Each interior angle measures 144 degrees
Each interior angle of a decagon is 144 degrees.An exterior angle is 180 - measure of interior angle.There exterior angle of decagon is 180-144which is equal to-36
The total degree measure in a decagon is 180(8) since a decagon can be broken up into 8 triangles. In a regular decagon, each angle has the same measure: 180(8)/10=18(8)=144. The supplementary angle, 36, is therefore the angle between the side bc and (each of) the two extended sides ab, CD outside of the decagon. The remaining angle, k, of the triangle thus formed is 180-2(36)=180-72=108. A sneaky way to get the same answer is to notice that if we extend every other side of the regular decagon, we get a (larger) regular pentagon. The angle k is one of these angles, so it is 108.
The measure of an exterior angle of an equiangular pentagon is 72 degrees. An equiangular pentagon is a regular pentagon that has five equal sides and five equal angles. An interior angle of a pentagon is equal to 108 degrees.
Each interior angle of a regular 10 sided decagon measures 144 degrees
Interior angle: 144 degrees
The measure of the entire interior of a regular decagon is 1440 degrees. 1440 divided by 10 equals 135 degrees. Therefore, 135 degrees is your final answer.

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
36 degrees.Exterior angles always add up to 360. So 360 divided by 10 is 36. Which means 36 is the measure of one exterior angle.360/10 = 36 degrees
