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 degree of a decagon?
1440 degrees, and every internal angle is 144 degrees
What is the degrees of 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 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°
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
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
