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
What is the interior and exterior angle of a decagon?
1980 degrees
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 measurement of a regular exterior decagon?
Each exterior angle 36 degrees Each interior angle 144 degrees A decagon has 10 sides
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.
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 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 exterior angle of a decagon?
Exterior Angle for a decagon is 36 Degrees.
What is the measure of each interior angle of a decagon?
144˚
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 of an interior angle of a decagon?
Each interior angle of a regular decagon is 144 degrees
What is the interior and exterior angle of a decagon?
1980 degrees
What is the interior of angle of a decagon?
Each interior angle of a regular decagon is 144 degrees
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.
