The interior angles of a decagon sum to 8*180 = 1440 degrees.
If it's a regular 10 sided decagon then each interior angle is 144 degrees which gives it a total sum of 1440 degrees
Sum of the interior angles of a decagon = 180*(10-2) = 180*8 = 1440 degrees. Since each interior angle of a regular polygon has the same measure, each angle of the decagon = 1440/10 = 144 degrees.
A ten-sided polygon. The sum of the angles of a decagon is 1440°. so 1440°÷10=144° ---------------------------------------------------------------------------- The easiest way to calculate this is to calculate the exterior angle and use the fact that the exterior and interior angles are supplementary. Sum exterior angles = 360° → Each exterior angle of a regular decagon is 360° ÷ 10 → Each interior angle of a regular decagon = 180° - 360° ÷ 10 = 144°
The sum of the exterior angles in any polygon is 360 degrees.Therefore that polygon is a decagon.
Any angle that you like. There are no constraints on a single angle of a decagon, only on their sum.
The interior angles of a decagon sum to 8*180 = 1440 degrees.
If it's a regular 10 sided decagon then each interior angle is 144 degrees which gives it a total sum of 1440 degrees
A vertex is the same as an angle. A decagon has 10.A vertex is the same as an angle. A decagon has 10.A vertex is the same as an angle. A decagon has 10.A vertex is the same as an angle. A decagon has 10.
Sum of the interior angles of a decagon = 180*(10-2) = 180*8 = 1440 degrees. Since each interior angle of a regular polygon has the same measure, each angle of the decagon = 1440/10 = 144 degrees.
A ten-sided polygon.

Sum exterior angles = 360° → Each exterior angle of a regular decagon is 360° ÷ 10 → Each interior angle of a regular decagon = 180° - 360° ÷ 10 = 144°
The sum of the interior angles in a decagon = 180(10-2) = 1440° The measure of a single interior angle in a decagon = (180(10-2))/10 = 144°
The sum of the exterior angles in any polygon is 360 degrees.Therefore that polygon is a decagon.
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 sum of interior angles of any N-sided polygon is: N*180° - 360°. For N = 10, this gives 1440°. Since the decagon is regular, all angles are equal, and each angle is 144°.
For any polygon, regular or otherwise, the sum of exterior angles is always 3600.
Each interior angle of a regular 10 sided decagon measures 144 degrees
