The internal angle of any polygon with n sides is equal to (n - 2) x 180 / n degrees. For example, each internal angle of a square is equal to (4 - 2) x 180 = 360/4 = 90 degrees.

What is the size of each interior angle of a regular decagon?
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°
What is the of an interior angle of a decagon?
Each interior angle of a regular decagon is 144 degrees
Calculate the measure of a central angle of a regular ten-sided polygon.?
Each interior angle of a regular 10 sided decagon measures 144 degrees
How do you calculate the exterior angle of a regular decagon?
Each of the INTERIOR angles are 36 degrees - therefore each exterior angle is 360 degrees minus 36 which is 324.
What is a decagons internal angle?
A regular 10 sided decagon has 10 interior angles that add up to 1440 degrees and each interior angle is 1440/10 = 144 degrees
What is the interior of angle of a decagon?
Each interior angle of a regular decagon is 144 degrees
What is the degrees of decagon?
1440 degrees, and every internal angle is 144 degrees
What is the degree of a decagon?
1440 degrees, and every internal angle is 144 degrees
How many vertices and angle does decagon have?
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.
What is the size of each interior angle of a regular decagon?

What is the exterior angle of a decagon?
Exterior Angle for a decagon is 36 Degrees.
What is the angle measure of each interior angle of a regular decagon?
The angle measure for each interior is 144 degrees each.Explanation: The angle measure of each interior angle of a regular decagon is 144°. Since a decagon is a 10-sided figure, replace n by 10 in (n − 2) • 180°. So the sum of the interior angle measures in a decagon is (10 − 2) • 180°, or 8 • 180° = 1440°. This is a regular decagon, so all ten interior angles are congruent. To calculate the measure of each interior angle in this regular decagon, divide 1440 by 10. The answer is 144°. 144 degrees is equal to 4/5 of 180 degrees
How do you work out exterior angle of an decagon?
You cannot. An exterior angle of a decagon can have any value.
What is the of an interior angle of a decagon?
Each interior angle of a regular decagon is 144 degrees
How much is each angle measure in a regular decagon 10 sides?
The external angles of a polygon total 360° . Therefore each external angle of a regular decagon measures 360/10 = 36° Therefore each INTERNAL angle measures 180 - 36 = 144°
Calculate the measure of a central angle of a regular ten-sided polygon.?
Each interior angle of a regular 10 sided decagon measures 144 degrees
What is the measure of one exterior angle of 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
