Also each exterior angle has a measure of 36.
Sum of interior angles of a decagon. A decagon has 10 sides and 10 angles. So the sum of the interior angles of a decagon is 1440 degrees. Since 1440 10 144 each interior angle in a regular decagon has a measure of 144.
36 interior angle 180 interior angle 144 sum of decagon interior angle 10 144 1440. Since the sum of the angles of a triangle is 180 the sum of the interior angles of a dodecagon is 8 180 1440. For a regular decagon all the interior angles are equal.
10 exterior angles of 36 36 summing to 360 360 10 interior angles of 144 144 summing to 1 440 1 440. So there s 180 36 144 left for the other two angles so each of those is 72. In many decagons the sum of interior angles will be 1 440 1 440 but that is not an identifying property because complex decagons will not have that sum.
Splits the decagon into 10 isosceles triangles. Hence the measure of each interior angle of regular decagon sum of interior angles number of sides interior angle 1440 10 144. The sum of the interior angles of a decagon is 10 2 180 1440 in a regular decagon all the angles are congruent at 1440 10 144.
The sum of the interior angles of a decagon is 10 2 180 1440 in a regular decagon all the angles are congruent at 1440 10 144. A regular decagon has equal interior angle measures. Decagon is a 10 sided polygon.
A decagon has 10 sides and 10 angles.
