What is the sum of the interior angles of a regular decagon?
1440 degrees. The sum of the interior angles of any regular polygon of n sides is equal to 180(n - 2) degrees.
What is the total interior angles of a decagon?
1440 degrees. The total exterior angles of a polygon is always 360 deg. Each interior angle plus its corresponding exterior angle is 180 deg. The sum of all interior plus all interior for a decagon must therefore be 1800 deg. Hence sum of interior angles is: 1800-360=1440 deg.
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 sum of interior angles of a convex decagon?
Not only convex, but all decagons:decagons have 10 sides implies Sum = (10-2)*180o = 1440o.
What polygon has an angle sum of 1440?
A 10 sided polygon or a decagon has interior angles that add up to 1440 degrees
What is the difference in the sum of the interior angles of a decagon compared to a triangle?
The sum of the interior angles of a decagon is 1440 degrees The sum of the interior angles of a triangle is 180 degreesThe difference in the sum of the interior angles of a decagon compared to a triangle = 1440 degrees minus 180 degrees = 1260 degrees
