What is the interior and exterior angle for a regular decagon?
A decagon is a polygon with 10 sides. By using the interior and exterior postulates, you can find the angle measures, which happen to be 144 and 36 degrees respectively.
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°
How many sides does a regular polygon have if one interior angle is 144?
It is a decagon (10 sides) because if the interior angle is 144° then the exterior is 36°. 360 Divided by 36 is 10 and so it is a decagon.
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 the of an interior angle of a decagon?
Each interior angle of a regular decagon is 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
What is the interior and exterior angle for a regular decagon?
A decagon is a polygon with 10 sides. By using the interior and exterior postulates, you can find the angle measures, which happen to be 144 and 36 degrees respectively.
What is the measurement of a regular exterior decagon?
Each exterior angle 36 degrees Each interior angle 144 degrees A decagon has 10 sides
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 exterior angle of a decagon?
Exterior Angle for a decagon is 36 Degrees.
Interior angle of a decagon?
To find the interior angle of any polygon. Exterior Angle = 360 / n ( the number of sides) Interior angle = 180 - exterior angle. So for a decagon ( 10 sides) Ext angle = 360 / 10 = 36 Int angle = 180 - 36 = 144.
What is the measure of an interior angle for a regular ten-sided polygon?
144o. Sum of exterior angles of a polygon is 360o. Each exterior angle for a regular decagon is 360o / 10 = 36o. Exterior and interior angles are supplementary, that is sum to 180o. Therefore the interior angle of a regular decagon is 180o - 36o = 144o.
How much is each angle in an decagon?
Providing it is a regular decagon of 10 sides then:- Each exterior angle: 36 degrees Each interior angle: 144 degrees
What is the measure of each interior angle of a decagon?
144˚
How do you work out exterior angle of an decagon?
You cannot. An exterior angle of a decagon can have any value.
How many sides does a regular polygon have if one interior angle is 144?
It is a decagon (10 sides) because if the interior angle is 144° then the exterior is 36°. 360 Divided by 36 is 10 and so it is a decagon.
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.
