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
The 10 interior angles of a decagon add up to 1440 degrees
The interior angles of a 10 sided decagon add up to 1440 degrees.

A decagon
1440 degrees
The sum of the interior angles is 1440 degrees.
No because the interior angles add up to 1440 degrees
The sum of the interior angles of a dodecagon (not duo-decagon) is (12 - 2)*180 = 1800 degrees.
